Sometimes all you need is three
Turn 1: Quicksilver (101)
Turn 2: Forge (45) if you have it, otherwise you probably don't want to Forge ever except on Brood (20)
Turn 3: Literally any 3 cost card except for Silver Surfer (260), if you got the Forge prioritize Brood
Turn 4: Another 3 cost card (Hopefully your hand is not Magik (76) Sera (112) Odin (93) at this point)
Turn 5: Magik or Sera, or a three cost
Turn 6: If you played Sera, now is the time for two three costs and then Silver Surfer, if you played Magik, you can either play two three costs or if you have her, Sera. If you have neither, hope that two three costs can win you the game
Turn 7: If you got here, Surfer then Odin should be possible unless your draws were very bad. If they were, you still have more than enough energy for three three cost cards, just make sure Silver Surfer is last
The other cards in the deck are sort of for control, you have Storm for lockdown, Killmonger for getting rid of quicksilver to open you up more and to get rid of some of their things, and Rhino for location control.
