Have to think about Wraiths, its just alot of mana then, have to test it. Good point though.
And ye, ill add 1 + 1 basic lands to the list now that you enlightened me, forgot about that totally.
About necropotence. It is very good card but the problem is that i usually go for combo turn 1 - 2 so i dont have even time to cast it or mana cause its spent to tutoring turn 1 or doomsday turn 2. And 2nd, it eats alot of life and with doomsday + thoughtseize ( as u suggested ) you'll be so low on life that opponent could just finish u before combo goes through. At least Fish / aggro decks. Ive been trying thoughtseizes too, but usually i have 2-3 black cards i dont need at that moment ( turn 1 ) so i can use it to Unmask and then use the mana for something else like A-Recall or ponder or so on, or even another disc. Last the pact -> If i have any mana source in my hand and no counters before casting doomsday i always add pact to the 5 cards cause i usually win the game that turn if no one uses counter, and if uses then i have pact. If its in starting hand or so i can always use it to FoW or MisD.
Ill add the basic lands now and test still abit more with thoughtseize.
More comments would be nice off course.
I thought about the Wraiths allready and basicly it doesnt speed it up at all, then you just postpone your combo by 1 turn gathering up mana before you launch, but then the opponent doesnt know that your doing it. Bad thing in this is that if you dont have counter in your hand your kind of screwed cause your 5 cards has to be : A - call, Black Lotus, Dark Ritual, Mind's Desire and Beacon. So no pact this time then. And you need 3 base mana, or 2 + 1 mox or 2 + black lotus / petal to launch. So not possible at turn 1, or might be with EXACTLY right cards and possibility is like 1-3 % for that

. Ill try the deck with 1 Wraith today.
Does anyone has any experience vs Stax with doomsday? Thats the only deck i havent played against with new build, and thats the one i fear the most. Some advices against stax ?
