Grinning Bugaboo

Menace, haste

Whenever Grinning Bugaboo deals combat damage
to a player, that player reveals cards from the top
of their library until a creature card with converted
mana cost 2 or less is revealed. Place that card onto
the battlefield under your control. That player
shuffles their library.

Whenever a creature you control but do not
own would die, exile it instead.
