Yuna, Grand Summoner

Grand Summon — {t}: Add one mana of any color.
When you next cast a creature spell this turn, that
creature enters with two additional +1/+1 counters
on it.

Whenever another permanent you control is put
into a graveyard from the battlefield, if it had one or
more counters on it, you may put that number of
+1/+1 counters on target creature.
