During an idle moment I strolled through unicorn way with the deckathalon deck to try it out. It looks viable. Treasure mage? Artificer? You get all of your health, mana, and stat bonuses. Almost a normal mage except all the spells they cast are from their equipment, pets, or from treasure cards. I mean some pets give 5 or more spell cards by themselves.
End-game wizards have no reason to do this, but starting a boss battle in Celestia with three power-pips would have been like a dream.
Are any of you running around as baby wizards and beating the snot out of bosses that simply aren't prepared for your speed? Bonus points if you are only using equipment/pet spell cards with treasure card reshuffles!
