Booga, The Boggfather

Whenever a goblin enters the battlefield under
your control riot.
{b}{r}{g}: All goblins you control gain your choice
of Trample, Menace, or Deathtouch until end
of turn.
{b}{r}{g}: Sacrifice a non-land permanent. Each
opponent sacrifices a permanent of the same
type. If a goblin is sacrificed this way draw
a card.
