I already addressed the fact that there is no maindeck disruption. The maindeck is very tight right now, and the only card I would take out for maindeck Durreses is Cabal Ritual. BTW, al that you said I already addressed. "This deck has the weaknesses of any Storm deck." That means it looses to Pillar, Trinisphere, Chalice, Sphere of Resistance and Null Rod. Often, though, you can win before those crads are even in play. Please, test the deck before posting. Otherwise the post just ends up as a repetition of an already established fact. BTW, there is now disruption maindeck.
This does not have the weakness of other storm decks. It dies to a single duress or FOW on helm. Without helm, you can do _NOTHING_. Other storm decks can draw more cards from draw 7's etc.
Don't give me crap about testing your pile of eggs.
It is your job to test your deck. If you don't want criticism, don't post a decklist.You had that much spare mana you could move mana sources out of maindeck? When do you side in rituals? I am seeing 18 mana sources main.. again, you better hope to god you get a fast helm.
In combo decks you should never really have to side in and out mana sources, it means you have too many/too few. There are a _FEW_ exceptions like vs. certain control/lock decks with rector trix I would side out a mox diamond as it was only useful on turn 1-2 kills and not on the longer term kills I was planning. But taking out 3 mana sources from a list you presented? That seems pretty harsh.
