Poompa, the Donut King

At the beginning of each upkeep, each player
creates a food token.
Whenever a player sacrifice a food, Poompa
explores.
When Poompa deals combat damage to a player,
you may instead have that player gain X life and
you gain twice X life, where X is Poompa's power.
He always knew where everything in town was
and was always willing to lend a hand
