Starts okay but then after the 16th level or so difficulty spikes unreasonably and you can't catch up to damage using upgrades because you need cards for your heroes and you don't get them as often or you have to buy them with real money. You need cards to unlock new heroes too. The initial ones aren't that strong.
Another thing is the time limit on the matching, sometimes it's fine, but a lot of times it ends before you make another move and ruins your turn.
