If you want easy mode use necromancer and spam skeletons, just pour a ton of points into max mana and some for hp as well. There is no limit to how many skeletons you can summon so go ham. had 10+ skeletons on the final floor and simply watched the massive war ensue while eating popcorn.
the rare and epic evo crystals are too expensive, especially the upgraded epic evo, shouldn't you be able to make enough money to upgrade a card by the time its maxed its exp? its possible with rare evos but even then, you're stuck spending all your earnings on 1 card while the rest are left with max exp.
