The Idea at all: A Super Hero Cardgame. Super Heroes often use elements!
A classic card game with a massive range of super heroes fighting against
each other with their individual elementary skills.

AND ACTION! ...
... Homlander is at the row and makes his next move.
his eyes turn red and went into a mitghy fireball and he takes 2 lives from you.
you are allowed to advance 1 field in forward directions
before the next hero will take his turn.

popcornflood uses his power up card to increase
Homelander's damage with the breastmilk.
(sorry @popcornflood that was such a funny comment from you!)
