Infinaut/Discard

The primary win condition for this deck is to discard powerful cards and bring them back with Hela. This works well with high power cards like Hulk and Infinaut. Swarm/Wolverine help protect you from losing cards when discarding. Sword Master and Black Cat are powerful in their own right. When it makes sense, Morbius can be used as well for a power boost.

Playing Infinaut on turn six is a secondary win condition, especially if you can build up Sunspot and protect it with armor. Cards like Black Cat and Sword Master are powerful enough to help you win a Sunspot lane.

Captain Marvel is a bonus and will win you games. A great play on turn five (or even 6) if you are not going to play Infinaut.

Hell Cow could be swapped in for Sword Master, and can potentially help you discard more cards to bring back with Hela and buff your Morbius, but it adds an element of extra risk, and costs more than Sword Master for the same power.
