Aka, Lord of Putrefaction

Deathtouch; menace
When a card would enter the graveyard from
your library, each player loses life equal to its
mana cost.
When Aka, Lord of Putrefaction dies, exile it
instead. When you do, you get an emblem with
"At the beginning of each player's upkeep, they
return each creature card in their graveyard to
the battlefield. They gain haste."
