Kimberly, New Era Ninja

Ninjutsu {2}{u}{r}
Whenever Kimberly attacks or when it enters the
battlefield attacking, exile up to one instant or
sorcery card with mana value equal to or less than
Kimberly's power from your graveyard and put a
song counter on that card. Then, copy up to one
spell you own in exile with a Song counter on it
and cast the copy without paying its mana cost.
