I got a bunch of summons, shields and a few buffing cards for a deck with only a sword as an actual weapon. After a couple runs with it, I think the artist's clay should duplicate the actual summon itself with all its buffs/shield/thorns instead of base stats. With the existing summon-support cards (which could be better), it should be balanced. If not, the rarity could be increased since it seems like it should be rare. The game looks like it has a LOT of potential based on how simple yet fun it is right now.
