Horde Warchief Vol'jin

Magecraft —
Whenever you cast or copy an instant or
sorcery spell, choose target creature you control.
Until end of turn, it gains
"If this creature would leave the battlefield,
exile it instead of putting it anywhere else"
and "When this creature is put into exile,
create a 4/4 blue and red Elemental creature
token."
(Each instance of that ability triggers separately.)
"For da horde."
