This deck wasn't my idea, I saw a YouTuber by the name of Happy Durian come up with it. Basically, you'll be using Moon Girl to duplicate She Hulk and Infinaut on Turn 4 and skip Turn 5 while Quinjet makes them cost 1 less. That will give you a 0 and 1 cost She Hulk and a 5 cost Infinaut on turn 6.
Sunspot is there to soak up the Turn 5 energy and The Collector gets buffed from Moon Girl's hand duplication. .
Armor protects your Sunspot and the all-important Quinjet. Scarlet Witch gets rid of those pesky locations such as Dream Dimension (that makes your cards more expensive) and Mindscape where you'd be giving your opponent your big guns.
Cosmo and Shang Chi are super useful when you can't pull off your double Shulkies and Infinaut combo. Taskmaster and America Chavez are there for backup.
I've done pretty well, so far, with this deck and already got about 20 levels with it.
