The EPIC Storm is the best Ad Nauseam deck in legacy. Between Chrome Mox to act as additional copies of Lotus Petal as well as a lower average converted mana cost, Ad Nauseam has an increased power level here. Our primary storm engine and game plan, we’ve catered our deck to maximize its potential.
Something to keep in mind that Ad Nauseam is an instant, you can cast the spell in response to a Brainstorm or on an end step. There’s also the “Chrome Mox trick” – which is to cast Chrome Mox, in response cast Ad Nauseam, and in response to Ad Nauseam activate Lion’s Eye Diamond! You do this in order to be able to imprint after Ad Nauseam has resolved and is only viable if you didn’t have a card you could imprint prior to casting Ad Nauseam.
