With all the low CMC spells, Raven's Crime becomes a real nuisance, essentially turning any land I draw after turn 3 or 4 into a discard spell that combos with any (and sometimes multiple) Waste Nots I may have on the field to provide blockers, more spells, or extra mana to keep the train rolling

Trapjaw Tyrant I did mention that I don't like Banisher Priest effects, but Trapjaw Tyrant has enough going on to make it an all-star in Dinosaur Tribal lists: it's a 5/5 Dinosaur for 5 cmc and the best versions of Dinosaur Tribal will have reliable ways to trigger enrage, letting you remove more than one creature for at least a little while
