roguelike and decks should never be mixed 

you see deck builder then your like "okay only starting deck is crap but  after few plays i can earn some cards" cept you don't you make your deck on fly and are at mercy of rng 

art is decent even if its ai art and what little sound there is great.

IMHO anything with a deck and cards you should always be working towards owning the entire set instead of throwing out your deck after every match.
