My best advice with this deck is not to wait. If you can discard Infinaut with Blade, do it and don't wait to find Black Knight and hope you can still discard Infinaut then.
It wins as often by being boring old Shuri Red Skull Taskmaster as through Knight and Ghost Rider, but the power of the discard shenanigans I think certainly rivals what the Sauron package brings to the deck.
I am unsure about Dracula being in the deck and possibly it should be any of Giganto, Nebula, Armor... I think Luke Cage is the right call for his spot though.
Edit: after testing Dracula has come out for Giganto. I did significant testing with Magik in the deck and the deck was worse that way, at least in Conquest, despite the options it gives you to do for example turn 4 Shuri, turn 6 40 point Infinaut, turn 7 40 point Taskmaster, or to do Lady Sif into Ghost Rider on one turn. Giganto has been the most successful.
