Charcharothan

Frenzy (Whenever a creature with Frenzy attacks
with another creature that shares a creature type
those creatures get +1/+1 and Trample until end of
combat)
When Charcharothan enters, give each opponent a
Chum artifact token with, "{4} Sacrifice this artifact,
pay 5 life: draw 3 cards"

Defending player with a chum token can't block Charcharothan
