Etched Monstrosity isn't affected by the EtB denial effect, in this deck it's just a worse
Leveler.
Also, since every EtB create here are read with just their other abilities, it'd be best to have a playset of of
Dust elemental and remove the
hunted lammasu.
Other than that, I'd say there's too many EtB creatures and too few EtB denial cards, they're essential to this deck as the othee creatures are very, very bad without them. It would be best to have a playset of both and ways to get them quicker (tutors, filtering, looting, scrylands, etc). You're screwed if you don't get the orb or the tocatli guard or if they get out of play before you can put a creature into play.
