Instead of getting an immediate refill on energy and stamina I'd rather get tokens for free refills when I could actually use them. Too many times I've levelled up with near full energy.
I'd like to see a sort of modified standard tournament that would prevent players from having more that one of any given card in their deck. Without spamming you'd have much more interesting matches. I may be alone on this thought though. Prepare to be voted down, guy.
mimic should either be capable of mimicking every skill or target only skills it can use. I'm tired of my guys always targeting evade or counter units when strike or heal or anything useful is in play.
It's kinda stupid that you loose the level if the good pets fall off screen considering that you can click them out of existence. It shouldn't matter how they're destroyed, so long as they are.
