Chat GPT と作る EDH - 創造の座、オムナス/Omnath, Locus of Creation
きっかけ
周囲で複数の方が AI と対話してデッキを組んでいるのを見て、本職でも触れるケースが少なくないこともあり、自分でもやってみることにしました。
何を作る
Chat GPT の特性上、2023 年 4 月現在の無償版では 2021 年までの情報で結果が出力されます。最近のカードパワーと比べるとどうしても劣るカードが出てくることもあるので、そこは受け入れていく必要があります。また、時に正しくない情報が出力されるケースもあります。ある程度判別できるところから着手したほうが良いため、一番慣れている 創造の座、オムナス/Omnath, Locus of Creation で試してみることにしました。
初期設定
Hello. You are a Magic the Gathering deck-building consultant. Today you will help me to build an EDH deck with omnath, locus of creation as Commander.
Chat GPT が振る舞う Role を指定することで想定した動きをしてくれるケースが多いのはよく知られているので、このように定義してみました。すると以下のようなパーツを早速出力してくれました。
Omnath, Locus of Creation is a powerful legendary creature that benefits from having a diverse mix of land types in your deck. To get the most out of Omnath, you'll want to include plenty of land ramp cards, such as [[Cultivate]] and [[Kodama's Reach]], to help you get ahead on mana and trigger Omnath's abilities. This deck includes plenty of land ramp cards, which will help you trigger Omnath's abilities and cast your more expensive spells. It also includes a number of powerful creatures and spells that can help you close out the game, such as Avenger of Zendikar and Craterhoof Behemoth. Additionally, there are a number of enchantments and artifacts that can help you generate even more value from your lands, such as Exploration and Crucible of Worlds.

Omnath, Locus of Creation は、デッキに多様な土地タイプを混ぜることで恩恵を受ける強力な伝説のクリーチャーです。Omnath を最大限に活用するためには、[[Cultivate]] や [[Kodama's Reach]] など、マナを先行させてオムナスの能力を誘発させるのに役立つ土地ランプカードを多く入れたいところです。このデッキには、Omnath の能力を誘発させ、よりマナコストが大きい呪文を唱えるのに役立つ、土地のランプ・カードがたくさん含まれています。また、ゼンディカーの報復者/Avenger of Zendikar や 孔蹄のビヒモス/Craterhoof Behemoth など、ゲームを締めくくるのに役立つ強力なクリーチャーや呪文も数多く含まれています。さらに、《探検》や《世界のるつぼ》など、土地からさらなる価値を生み出すのに役立つエンチャントやアーティファクトも数多く含まれています。
デッキが 62 枚しかなかったり、このままだと青マナが不足して Omnath が場に出せないのではないかという辺りは気になりますが、なかなか悪くない出だしだと思います。なにより解説が素晴らしいですね。ということで、不足しているカードの候補を作ってもらいましょう。
I appreciate your quick drafting. It will be beneficial. By the way, EDH should consist of 100 sheets, including Commander. This list has only 62 cards. What kind of cards do you think we should add?
すると以下のような候補を出してくれました。
おお、なかなかの顔ぶれのカードが出てきました。禁止カードが入っていたり、一気に 100 枚を超えてきているのがお茶目ですが、ひとまず土台としては十分ですね。コンサルタントに相談する体裁で少しずつまとめていきましょう。
マナ基盤を見直す
土地の見直し
ひとまず今のリストだとマナ基盤が厳しいのは明らかなので、ここから直していきましょう。まずは前提条件を聞いてみます。
Thank you for expanding on the idea. It looks very nice. I would like to gradually get the deck ready. How many lands should we employ first?
A good starting point for the number of lands in an EDH deck is usually around 36-38. With a land count in this range, you should be able to cast your spells consistently without getting mana flooded or mana screwed too often.
For an Omnath, Locus of Creation EDH deck, I recommend starting with 36 lands and then adjusting the number based on your playtesting. Remember that the number of lands you need may vary based on the rest of your deck's composition, such as the number of mana rocks and ramp spells you have, so it's important to experiment to find the right balance.
Also, keep in mind that you want to include a variety of different types of lands in your deck, such as basic lands, dual lands, and utility lands. You can use the list of lands I provided earlier as a starting point and make adjustments as necessary.
なるほど。とりあえず現時点で 53 枚ほど土地が選択されているので、どんなバランスが良いか候補を出してもらいましょう。少し根気のいる議論になってしまったので、ダイジェスト形式でお送りします。
I agree with you. Please try to select 36 of the potential lands you have considered adopting so far.
--
Sure, here is a list of 36 lands for your Omnath, Locus of Creation EDH deck, based on the options I provided earlier:
(色々なランド)
9 Forest 4 Mountain 4 Plains
This selection of lands should provide you with a good balance of color fixing, utility, and basic lands to support your deck's mana needs. Remember to adjust the number of lands as needed based on your playtesting, and feel free to make any substitutions or changes that fit your playstyle and preferences.
I am concerned about the number of basic lands and whether the color balance is maintained. Also, is there any problem with the lack of islands?
--
You raise a valid point about the number of basic lands and color balance. The land list I provided earlier had a total of 18 basic lands (9 Forests, 4 Mountains, and 4 Plains). While this distribution may work for some decks, it's possible that your deck may require a different balance of basic lands to ensure that you have the right colors of mana available when you need them.
To address this, you could consider adjusting the number and distribution of basic lands in your deck to better match your needs. For example, if you find that you're frequently running into issues with not having enough red or blue mana, you could consider swapping out some of the basic Forests for basic Mountains or Islands, respectively.
Regarding the lack of Islands, it's worth noting that this can limit your ability to cast spells with blue mana requirements. However, since your commander, Omnath, Locus of Creation, only requires green, white, and red mana, it's possible to build a successful deck without including any Islands. That said, including some blue sources in your mana base, even if they aren't Islands, can still be helpful for casting spells that require blue mana.
Overall, the key is to find a balance that works well for your specific deck and playstyle. You may need to experiment with different combinations of lands to find the right balance of colors and utility for your Omnath, Locus of Creation EDH deck.
Omnath, Locus of Creation needs one each of blue, red, white and green, right?
---
My apologies, I made a mistake in my previous response. You are correct that Omnath, Locus of Creation requires one of each color of mana, including blue, green, red, and white.
With that in mind, it's even more important to ensure that your deck's mana base has a good balance of all four colors of mana to support your commander's abilities and the spells in your deck. You may want to adjust the number of basic lands or non-basic lands to ensure that you have the right mix of colors available when you need them.
---
Thank you for confirming. Now please take this into account and select the 36 pieces of land again.
---
Sure, here's an updated list of 36 lands that takes into account Omnath, Locus of Creation's color requirements:
（基本地形を含まない 35 枚の特殊地形 with Prismatic Vista）
This selection of lands includes a good mix of colors, and should provide you with the flexibility you need to cast spells with Omnath, Locus of Creation and support your deck's strategy. As before, you may want to adjust the number or types of lands based on your playtesting and personal preferences.
Thank you very much. I checked and it appears to be 35 sheets. Also, there are no basic lands in the game, so it is not possible to search for lands from Prismatic Vista. Please select 36 again. I am looking forward to it!
--
I apologize for the confusion earlier. Here is an updated list of 36 lands that takes into account the changes you mentioned:
（基本地形を含まない 36 枚の特殊地形 with Evolving Wilds）
This new list should work well for your Omnath, Locus of Creation EDH deck. It includes a good mix of colors and utility lands, as well as some basic land tutors to help you find the lands you need. As before, you may want to adjust the number or types of lands based on your playtesting and personal preferences.
Great, we are now down to 36 cards! Unfortunately, Evolving Wilds also requires basic terrain to search for lands. Now that we know that fetch lands work well with Omnus, how about 36 land selections, including Plain, Forest, Island, and Mountain, one for each to take advantage of Evolving Wilds and Prismatic Vista?
--
My apologies for the confusion earlier. Here's an updated list of 36 lands that includes one basic land of each type so that you can take advantage of cards like Evolving Wilds and Prismatic Vista:
1 Plains 1 Island 1 Swamp 1 Mountain 1 Forest
(31 枚の特殊地形の束 with non Evolving Wilds and Prismatic Vista)
--
Swamp is not required; Please choose 36 lands again without Swamp.
--
I apologize for the oversight. Here's an updated list of 36 lands without Swamp:
1 Plains 1 Island 1 Mountain 1 Forest
1 Arid Mesa 1 Bloodstained Mire 1 Breeding Pool 1 Canopy Vista 1 Cinder Glade 1 Command Beacon 1 Command Tower 1 Exotic Orchard 1 Field of the Dead 1 Flooded Strand 1 Hallowed Fountain 1 Misty Rainforest 1 Myriad Landscape 1 Naya Panorama 1 Opal Palace 1 Overgrown Tomb 1 Path of Ancestry 1 Prismatic Vista 1 Reliquary Tower 1 Rootbound Crag 1 Sacred Foundry 1 Scattered Groves 1 Sheltered Thicket 1 Spire Garden 1 Stomping Ground 1 Sunpetal Grove 1 Temple Garden 1 Temple of Abandon 1 Temple of Malady 1 Temple of Plenty 1 Valakut, the Molten Pinnacle 1 Verdant Catacombs 1 Wooded Bastion
この辺りかなり苦労しました。一定程度前提条件を明確にするプロンプトを挟んだ方がうまくいった可能性が高そうですね。雰囲気は分かったので、これまで抽出していただいたカードを元に、機能する形に整えて 36 枚選んでおきます。
マナ加速の選択
経験上 3 ターン目には Omnath を出すことが重要なことは理解しているので、Ramp カードの選択について議論をしていくことにしました。土地で苦労したので、少し具体的な前提条件を付けて会話してみます。
Thanks to you, we have made a satisfactory choice about the land. Next I would like to think about mana acceleration, I would like to aim to cast Omnath on turn 3, but how much less than 2 mana acceleration would I need to do that?
---
To consistently cast Omnath, Locus of Creation on turn 3, you'll want to have at least two sources of mana acceleration in your opening hand. There are many cards you can use for this purpose, including some of the ones we've already discussed such as Sol Ring, Arcane Signet, and Farseek.
Other options for mana acceleration in a four-color deck like this one include:
Nature's Lore
Cultivate
Kodama's Reach
Rampant Growth
Three Visits
Sakura-Tribe Elder
Skyshroud Claim
Wood Elves
Steve, the Harvest Helper
Lotus Cobra
Exploration
Burgeoning
By including several of these cards in your deck, you should be able to consistently cast Omnath on turn 3.
"Steve, the Harvest Helper" does not exist on the MTG card, does it? Also some cards are 3 mana or more and don't seem to contribute to playing Omnath on turn 3. Please list 20 cards that are 2 mana or less and contribute to playing Omnath on turn 3, taking into account their affinity with the omnath locus of creation. Cards raised so far are also fine.
---
I apologize for the confusion, "Steve, the Harvest Helper" was a joke response.
Here are 20 cards that are 2 mana or less and can help you accelerate your mana in order to cast Omnath, Locus of Creation on turn 3:
Sol Ring
Arcane Signet
Farseek
Nature's Lore
Cultivate
Kodama's Reach
Rampant Growth
Three Visits
Sakura-Tribe Elder
Elvish Mystic
Llanowar Elves
Fyndhorn Elves
Birds of Paradise
Wild Growth
Utopia Sprawl
Carpet of Flowers
Exploration
Burgeoning
Mana Crypt
Chrome Mox
These cards are all relatively cheap and efficient, and many of them also have synergy with Omnath, Locus of Creation's abilities. Sol Ring, Arcane Signet, and Farseek are particularly strong choices because they can help you fix your mana and ramp at the same time. However, keep in mind that you may want to adjust the number of mana acceleration cards you include based on your personal playstyle and the overall composition of your deck.
いくつか無色しか出ないマナ加速が含まれていますが、前向きに考えれば 3 マナの 木霊の手の内/Kodama's Reach を２ターン目に唱えるために使うこともできそうです。意見を尊重しつつ良いバランスを探っていく議論をしてみます。
Sol Ring, Mana Crypt can only produce colorless mana but it accelerate the mana curve and we can play high value cards like Kodama's Reach. This is a good finding for me.
---
That's correct! Sol Ring and Mana Crypt are both powerful mana accelerators that can help you cast higher value spells like Kodama's Reach earlier in the game. While they do produce colorless mana, they can still be very useful in a deck like this one that relies heavily on ramp and color fixing. Just be sure to include enough other sources of colored mana to make sure you can cast all of your spells when you need to.
---
How many colored mana accelerators and colorless mana accelerators would be appropriate in this deck?
---
The ideal ratio of colored vs. colorless mana accelerators in your deck will depend on a few factors, such as the overall composition of your deck, your preferred playstyle, and the specific mana requirements of your spells.
As a general rule, you will likely want to include a mix of both types of mana accelerators to ensure that you can both ramp quickly and fix your mana colors as needed. A good starting point might be to include around 8-10 colored mana accelerators and 4-6 colorless mana accelerators. This will give you a solid base of ramp and mana fixing, while still allowing you to play high value spells like Kodama's Reach and similar cards.
However, this is just a general guideline, and you may want to adjust the ratio of colored vs. colorless mana accelerators based on your personal preferences and the specific needs of your deck. Be sure to playtest your deck thoroughly to see what works best for you.
---
Let's discuss the mana balance needed to cast Omnath on turn 3 with 4 colors of mana.
---
Sure, let's take a closer look at the mana requirements for casting Omnath on turn 3 with all four colors of mana.
Assuming you are starting with 3 lands in play and have a 2-mana accelerator in hand, you will need to generate a total of 5 mana on turn 3 to cast Omnath. This means you will need to have at least 1 source of each color of mana (green, white, blue, and red) by the time you get to turn 3.
To achieve this, you may want to include a mix of colorless and colored mana accelerators in your deck, as well as some cards that can help you fix your mana colors. Some good options might include cards like Cultivate, Kodama's Reach, Farseek, Sakura-Tribe Elder, and Rampant Growth for ramp and fixing, as well as cards like Chromatic Lantern and Coalition Relic for color fixing.
It's also worth noting that you may not always be able to cast Omnath on turn 3, depending on the specific cards you draw and the order in which you play them. However, by including a mix of ramp, fixing, and acceleration in your deck, you should be able to consistently cast Omnath early in the game and begin building up your board presence.
ここまでの議論を元にマナ基盤をまとめて以下のようなリストを作ってどうですかと聞いてみました。ひとまずこれでマナ基盤の見直しは完了です。
Thank you. We have selected 71 cards for the discussion so far, including 36 lands and a mana acceleration card. I will compile the list, but please let me know if there are any areas that might need to be modified.
---
The current list looks good to me. It includes a variety of mana acceleration cards that should help you cast Omnath on turn 3 with 4 colors of mana, and many of the cards have good synergy with the Omnath, Locus of Creation commander. However, keep in mind that you may want to adjust the list as you playtest the deck and identify any areas that need improvement.
