Grinning Bugaboo

Haste, menace
Whenever Grinning Bugaboo deals combat
damage to a player, that player searches their
library for a creature card. Put that creature onto
the battlefield under your control. Its owner
shuffles their library, then discards their hand
unless a creature they own entered the battlefield
under your control this way this turn.
Whenever a creature you control but do not
own would die, exile it instead.
