Putting a few things I came up with here, since I don't want to forget them.
Revive:
-spell card
-the last creature killed is summoned
-life card?
-maybe ~5 quantum cost
Mud:
-Earth card
-Probably a creature
-uses water quanta
-idk what it does
Edit: Comments? Thoughts? Nothing?
Edit: (July 18) Wind on the Water:
Need some ideas with this one
This is definitely an water card with a large cost
(water creatures gain +1|1, +3|1, and +5|2 during their next turns?)
I'm also thinking of a spell card that allows you to place as many cards as you want that are in your hand into your deck.
