Core Set 2021

Hunter's Edge | Sorcery | | Put a +1/+1 counter on target creature you control. Then that creature deals damage equal to its power to target creature you don't control. | Johann Bodin

Ornery Dilophosaur | Creature | Dinosaur | Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.) Whenever Ornery Dilophosaur attacks, if you control a creature with power 4 or greater, Ornery Dilophosaur gets +2/+2 until end of turn. | Jonathan Kuo

Sabertooth Mauler | Creature | Cat | At the beginning of your end step, if a creature died this turn, put a +1/+1 counter on Sabertooth Mauler and untap it. | Randy Vargas
