Hearthpwn

Oof, I made a couple of minions originally and changed the one i liked most to a spell for balancing reasons, forgetting that it had to be a minion.

Ah well, I already submitted so it's too late to change it now. I'll just have to live with my mistake u-u

I was wondering if I should change it to frozen instead, but that might be deviating from WC3 a little too much (I already had to pick different art.)
