Kul-go of Sun and Moon

Whenever a player casts a spell from their hand, you may exile it with three time counters on it,
and if you do, if it doesn't have suspend, it gains suspend.(At the beginning of its owner's upkeep, remove a time counter from that card. When the last is removed, the player casts it without paying its mana cost. If it's a creature, it has haste.)
Whenever an opponent casts a spell from exile, copy it. You may choose new targets for the copy.
