I love the Time Mage. As he keeps getting stronger every turn he doesn't wound a Boss, he is a great hero for late game. If he comes out early enough, the player with the most Mage treasure will really have to think about if they want to keep drawing him (and the other mages) or if they need to switch it up so they don't eventually take the two wounds. If you like your Epic Heroes to be strong, this is a great addition to your deck. Just make sure you add strong Epic Heroes of the other treasure types as well, otherwise everyone will just avoid Mage treasures or keep them low.
