Kukitaravin, The Mystic

This card enters with X +1/+1 counters, where X is
the number of multicolored spells in your graveyard.

If an spell you control would be countered or
removed, return that spell to your hand instead.

Whenever you cast an multicolored spell, you may
pay {w}{u}{b}{r}{g}, if you do this, copy that spell X
times where X is half this card's power, rounded up.
