Same here. My deck similar and is a little better but still can't get far on lvl 10. I've gave up trying.
Blame the terrible game balancing. + bug.
On lvl 10, Notice if the opponent plays a combo card on 2nd turn, then their card attacks right away. It's Pretty much impossible to win in that scenario. If opponent plays a 2nd individual card, then your card gets a hit off first.
