cEDH Deck Guide: Toxrill, the Corrosive

Our Toxrill list fits the Control archetype, being a deck that play more focused on holding opponents while slowly developing the board and generating value.

This deck is unlikely to be the fastest at the table, as farm lists are still quite common and with the disappearance of blue in cEDH matches, there is a possibility that our list is the only one with interactions.

If this is the case, it is essential to maintain the more control approach, to prevent your opponents from winning (as obvious as this seems) before the deck's power peaks and your opponents run out of steam.

The commander has a very prohibitive cost at seven mana, making it difficult to cast it at the beginning of the games.

Toxrill works as a way to spend infinite mana, since having infinite colored mana and it in the command zone, you can cast it and sacrifice it with its own effect to draw cards.

In addition, it also works as an asymmetric sweeper, which will kill your opponents creatures while, for each creature of an opponent that dies, it generates you a slug. The commander is quite impactful when entering the battlefield, adding a lot of value to you over time.

This deck has two different combo lines: Thassa Consult and Isorev.

Thassa Consult

Combo Condition: Thassa's Oracle and Demonic Consultation/Tainted Pact in hand, and enough mana to cast them.

1. Cast Thassa's Oracle

2. Respond to her ETB by casting the other spell in your hand, naming a card you don't have in your library, or continuing to exile until the last card.

On Oracle's ETB resolution, you win the game.

IsoRev

Combo Condition: Isochron Scepter and Dramatic Reversal in hand and at least 3 mana from artifacts (at least one being colored), and mana to cast them.

1. Cast the Isochron Scepter, imprint Dramatic Reversal.

2. Activate the scepter's ability, and if you have untapped non-treasure artifacts, tap them to generate mana and leave it in the pool.

3. Repeat step two until you generate the amount of mana you want.

Cast the Commander and sacrifice until you draw the entire deck, then cast Thassa's Oracle to win the game.

Ramps

This list has a good number of ramps (for control decks), all with as low mana value as possible, to efficiently have mana for interactions. However, it is important to find out when not to use mana for this, as your opponents will be faster than you and this can certainly put you in unpleasant situations if you use too much mana to speed up while opponents can finish the game.

Phyrexian Tower and Blood Pet are very synergistic with our commander who spawns Slugs, generating mana when we sacrifice creatures, and Toxrill creates creatures to be sacrificed.

The list also features rituals like Dark Ritual and Cabal Ritual, which grant you additional mana on specific turns, as well as Grim monolith and Mana Vault, which are positive rocks that combine really well with Isochron Scepter and Dramatic Reversal that can untap them to generate even more mana.

Tutors

Tutors, along with functional copies, are what guarantee the consistency of the deck, being able to search for the card you need for certain situations.

As we run black and blue, we are gifted with some of the best tutors like Vampiric Tutor, Imperial Seal, Mystical Tutor, Demonic Tutor, Merchant Scroll and Diabolic Intent, plus specific mana cost tutors like Spellseeker and Muddle the Mixture.

We also have Wishclaw Talisman, which is a reusable tutor if you have bounces to respond to its effect before it resolves.

Card Advantage and Cantrips

This list has as main card advantage engines that generate value throughout the game, such as Mystic Remora and Rhystic Study, and that punish their opponents by taxing spells or guaranteeing draws, whichever they prefer.

We have Necropotence that turns your life into extra cards in your hand, Notion Thief that turns your opponents' draws into your draws, and Lim-Dûl's Vault, which has the potential to organize your deck whichever way you prefer. We also have Dark Confidant, which generates an extra card in your hand at the cost of life.

In addition to the cards discussed above, the deck also has the three main cantrips that dig up to three cards and replace themselves in the hand for one mana, in addition to Gitaxian Probe which costs two life to look at the opponent's hand and replenishes itself.

Interactions

This is a huge package, and it covers all kinds of cards that somehow deal with your opponents' plays like bounces, removals, counterspells, target changes, copies and protections.

The large amount, and mostly instant speed, is precisely to keep this threat constant and delay the game, which is a good thing for you as you follow this deck's strategy.

The interactions were chosen because they are the best with their effects, have the lowest cost among the cards with this effect, or the most acceptable negative point.

Just as important as knowing when to interact is understanding when not to interact, as it's nearly impossible for you to be the only one at the table with interactions. Your objective is to control the field, but it's impossible to actively do this against all opponents at the same time, so focus on punctual and powerful pieces for developing their game plan and save the rest of interactions for others, don't try to respond to everything.

Stax Pieces

As a Control deck, it is important to have cards that will hinder all opponents in something, that's why we use some stax pieces, which delays opponents without spending many resources on it.

To impede tutors and take the consistency of opponents' decks, we have Opposition Agent and Ashiok, Dream Render that, in addition to hindering tutors, do something else. The Agent turns opponents' tutors into your own tutors, and Ashiok mill cards while exiling graveyards.

Notion Thief turns opponents' draws into your draws, and Narset, Parter of Veils stops your opponents from drawing cards, and gives you some card selection. Dauthi Voidwalker is a serious hate piece that allows you to cast one of the exiled spells.

Last, but not least, we have Wandering Archaic // Explore the Vastlands, which isn't a real stax piece, but gives your opponents two options: either they pay two more mana on their instants or sorceries, or allow you to create a copy of them.

Strengths

- The combo pieces are easy to be found, allowing early wins with a certain frequency.

- The commander can generate a lot of value over time at the table, generating mana and cards to enable victory while taking the opponents' creatures.

- The deck can handle other decks well without losing its strength.

Weaknesses

- The deck can't be the fastest, usually closing games after turn 4.

- The fact that blue is less present on cEDH tables makes it difficult for more controllable decks that will normally have to bear the brunt of interactions, as other players will not have as many answers.

- The Commander's high cost ends up being a challenge for the deck, since either it will be cast way into the late game, or you will end up risking casting it at the wrong time.

That's all for today

Stay tuned for another cEDH deck tech in the next weeks!
