One of the defining features of Legacy is its ability to house several sub-archetypes within each overall strategy. Storm is a perfect example of one of these overall strategies. Within Storm exists A.N.T., T.E.S., and the deck we’re featuring today, Doomsday. Doomsday is on average slower than most Storm variants, but it has the added benefit of being able to sculpt its draws, which means that it can play the long game much better that the other variants.

The main difference between Doomsday and other Storm decks is how it wins. More often than not, you will need to cast the namesake card, Doomsday. After you do, you essentially get to stack your deck for the rest of the game, allowing you to go off from a fairly low base. One of the main difficulties that players find when piloting this deck is the incredible amount of possible Doomsday piles that can be created. More than not, the piles involve multiple copies of Lion’s Eye Diamond to let you have mana for no cost at all, Ideas Unbound, which is essentially 2 mana draw 3 in this deck, and either Tendrils of Agony or Laboratory Maniac, depending on how the game has shaped up.


Other potential inclusions in a Doomsday pile are Rain of Filth, which can in certain situations be the most powerful mana producer in the deck, Chromatic Sphere, which is essentially 1 mana draw a card, Lotus Petal, which is a free mana, and any forms of disruption such as Duress or Abrupt Decay that are needed. Additionally, two copies of Sensei’s Divining Top turns each mana you have into a spell cast for Storm.


Note: After a Doomsday, you’ll want a way to access those cards this turn (especially the first one, which is usually Ideas Unbound). The best way to access those cards is through having a Gitaxian Probe in hand, so don’t fire off those Probes unless you need to!

The sideboard of this deck is just as wonky as the mainboard. City of Solitude is rarely seen in Legacy, but for an additional green mana, it transforms your Defense Grid into a more guaranteed protection card. Engineered Plague and Dread of Night protect against the small hate creatures that are abundant in Legacy, Abrupt Decay and Krosan Grip offer hate against most of the remaining troublesome cards, especially Counterbalance.

Shelldock Isle is an alternate win con when paired with Emrakul, the Aeons Torn after a Doomsday. It requires that you untap with it, however that is usually not a problem. When sideboarding in any of the green cards from the sideboard, a singleton basic forest comes in, especially against decks that rely on Blood Moon for disruption. Fetching a turn 1 forest to avoid getting hated by Blood Moon and then waiting to draw the hate card you need is not unreasonable at all.

Here are the changes I would make going forward:


No changes.


-1 Engineered Plague

-1 Karakas

+1 Emrakul, the Aeons Torn

+1 Duress
