I'm not sure if non-mage creatures should be able to receive smash tokens or not. On the one hand, walls only get destroyed by wall bashes, so you'd need push effects to deal smash tokens at all, so even if having a smash token during the reset phase could destroy a non-mage creature, it probably won't do that too often. But then again, if only mages can gain smash tokens, then nobody would have much reason to push non-mage creatures outside the Arena. In the original super smash bros video game franchise, the equivalent of non mage creatures would be assist trophies, and those went away after a certain amount of time elapsed, kind of like dissipate trait. However in Mage Wars it might work better to simply subject non-mage creatures to the same smash token rules but with fewer smash tokens. Maybe non-mage minor creatures die if they have one smash token during reset phase, and non-mage major creatures die if they have two smash tokens during reset phase? Not sure about this hmm....
