I mean... he is still just a 5/5 body that has to connect to do anything. He's not even particularly large compared to other 4 mana cards like Ripjaw Raptor or Territorial Allosaurus. Not particularly hyped about this guy. Seems good for Limited and probably unplayable in Standard.
I mean, this card just seems solid. The fact that the floor of this card is a 5/5 for 4 mana is pretty dang good. He seems like another part of the potential Sarkhan's Unsealing deck in standard, as you really want all your creatures to be both cheap and have 4 or more power. I'm just imagining a g/r stompy style deck where your only non creature spells MD are Unsealing and the new Fires of Yavimaya...that's a literal crap-ton of damage you can be throwing around.
I've been wondering for a while now when we were gonna see the on combat damage trigger that blows up enchantments and artifacts on a creature. The last one I remember being in standard was Polis Crusher.
