How do you even cast this in T3? Multiple Tooth of Chiss-Goria?
Haven't tested, but given it has no trample and limited resilience, I would not be concerned with it being too good. One awkward thing is how it does not synergize well with artifact creatures, upon which many artifact archetypes are designed. Sure, they can be sacrificed to bring it back, but at 11 mana, a cost reduction of at least 6 is needed to make it a real payoff.
