This is my current deck, it still needs some improvements but I have not collected all of Pool 2 cards yet.
There are a few things going on here:
Devil Dino is the main card you want + Moon Girl to make 2 copies of it potentially.
Collector to benefit from Moongirl
Ice Man and Cable to disrupt the opponent and gain early info about the kind of deck they might be playing
White Queen follows a similar logic, more info about the cards they have in their hand
Of course, Cable and White Queen also help with the Collector and keeping your hand big for Devil Dino in case you are not able to play MoonGirl.
Sunspot and America can be replaced, I am using Sunspot to make up for bad draws and bluff that I might play Infinaut, and America is to boost the draw for others and as a hail mary in case Devil gets knocked out.
Scarlet Witch is my favorite card, so her inclusion might be a bias, but still a really useful card for much-needed lane correction. -- Put in Storm for reliability
Be wary of decks with Shang-Chi, Enchantress, and Move Decks. Remember that there are some psychosocial games going on in this deck, it's meant to disrupt your opponent and help you strategies better.
