While it isnt too powerful on its own, with typal support like Coat of Arms, this card could become a pretty big threat in a myr deck
Giving a card in exchange for reasonably-costed exile removal that can hit enchantments is not to be sniffed at
Elves play into the middle ground, offering an easily growing board state, constant pressure on enemy life totals, while also requiring you to be on your toes as you learn not to play into large board wipes or Toxic Deluge effects
I just can't wait for this set to be released because of how many cool-looking cards there will be
Sure, if this stays in play for three or so turns then it is going to dominate the game but lots of cards fit that bill
If you manage to play Papalymo Totolymo, for example, he also deals 1 damage to each opponent, and you gain 1 life, whenever you cast a noncreature spell
