Rose, Mother of the Pit

Flash, flying
When you cast Rose, counter target spell, then
copy that spell's card. You may cast that card
without paying its mana cost. If you would cast
a card with {x} in its cost, you may pay any
amount of {p/c}. If you do, add that amount of
mana to X. While Rose is on the stack, if it's not
the first time she's been cast this game, she has
split second.
{p/u}{p/b}{p/r}: Return Rose to her owner's hand.
