What a surprise to see you here nico!
I like the way your cards work, it's the first time a card spawns creatures from another element by sacrificing itself. Very nice.
But although i like the card art (cerberus in particular seems to fit the game aesthetics perfectly) Zanz can't use it if the original artist is not aware of it, so he needs to know where it came from. Otherwise it'd be some kind of art theft. Try to get the site, or at least the links, it'd help a lot.
About the cards itself, hm, they seem balanced, and the sacrifice>spawn mechanic is unique and fun... maybe the stats-cost relation could be improved a bit.
Oh, and the spelling XD.
Glad to have you here, bro
Is there a specific reason why Cerberus and the demon hounds are different elements?
I THINK he tried to reinforce the already existent

synergy, but I won't speak for him
