Champion of Cunning ( f2p )

hi there,
its my 3rd or 4th day in this game, so i'm kinda pretty new.
still f2p n probably gonna stay f2p

this is currently my only deck, i got a champ pretty early on n luved it, so i decided to craft 2 additional.
with this list i managed to beat the diamond gauntlet. also i'm currently ranked silver 2.
so yea it allready is kinda good.

yet theres always stuff to change/improve. i'm open to any advice.
