This is Sam Black’s Ad Nauseam Tendrils (ANT) list from the MOCS Championship a few weeks ago.
Much like Lands, one of the big reasons to play a deck like Storm is that you get a bunch of free wins. Sometimes you get paired against a deck like Elves that has little chance of beating you, and you often will win game 1 against players who don’t know what you’re playing and thus don’t know what kind of a hand they need to keep, or players who don’t have the right cards in their deck yet to be able to stop you.
The deck is also fast and surprisingly resilient. It’s capable of playing through a lot of hate, including hand disruption and countermagic. The best cards to combat Storm are permanent-based hate—things like Chalice of the Void, Meddling Mage, Rest in Peace, Counterbalance, and so forth.
The addition of Dark Petition really helped Storm a lot by giving it more ways to play through hate, and more ways to find anti-hate cards. While permanent-based hate is the best way to fight Storm, Storm decks also have access to cards like Abrupt Decay after sideboard to fight it.
This is not a deck I would sleep on. It’s important to have a plan against Storm.
