Since Galactus got released today, I decided to make a deck that would make his mere 3 power be more of a menacing number. The basis of the deck is to dominate one zone and place Adam Warlock for extra card draw if needed. If you can get lucky and get Galactus in your opening hand and on the two left-most cards in your hand you can play the Nakia to buff him to 5 power, if not Okoye works fine, but only if he isn't in your hand (obviously).
Play Nova and Wolverine on the same location and preferably the second location that will be destroyed otherwise this won't work. On turn 5, play Forge as your last card of that turn. Then play Galactus and he should be at 7-10 power depending on how many buffs you got lucky with. Beast is also used on Okoye if you can sneak that in there before turn 5 and haven't drawn Galactus yet.
Lastly, the way the combo works, is:
Galactus gets played, his effect goes off, first zone gets destroyed, then the second one with Nova and Wolverine on it.
Nova buffs your cards, Wolverine gets put on the only available zone now which is Galactus' and you should win the game with either 10-13 power.
Also, replace Angel with anything you want, he's just a placeholder cause I don't have many good cards.
