use night crawler to fill up bar sinister on turn 4. move 1 night crawler in order to place a blue marvel there on turn 5. turn 6 move all night crawlers and put down onslaught on bar sinister. profit. usually around 20 power per card on the board. if you don't draw blue marvel it can be replicated with ka-zar.
armor is used to prevent your 1 costs from getting killmongered.
cloak is used to move ebony maw if needed.
every other card is pretty much replaceable.
ideally add adam warlock and magik so you can draw more cards and extend the possibility of pulling this off but i dont have those cards. if you dont have them add cards to fit curve and control board.
