Mr. Oogie Boogie

When Mr. Oogie Boogie enters the battlefield
create X 1/1 green and black Pest creature tokens
with " when this creature dies, you gain 1 life "
where X is the amount of creatures in your
graveyard .
{4}{b/g}{b/g} sacrifice a creature: each player discards
their hand and rolls a D6, then draws cards from
their library equal to their result.
"..boy I don't play fair."
