Frat Houndius, Master Wingman

Devour 2 (As this enters the battlefield, you may sacrifice any number of creatures. This creature enters the battlefield with two times that many +1/+1 counters on it.)
Banding (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)
