Put a black wizard creature card from your hand
onto the battlefield, then put a black wizard
creature card with converted mana cost X or less
from your library onto the battlefield, then shuffle
your library.
Flashback {2}{b} ( You may cast this card as an
instant from your graveyard for its flashback cost,
except its flashback cost is {0} if you control a black
wizard creature. If you do, instead its card text says
"Counter target spell", then exile it.)
