The Great & Powerful Trixie

Your instants and sorceries cost {1} less to cast
At your end step, you choose one opponent
and flip a coin:
If it lands on heads, you may cast an instant or
sorcery from the chosen players graveyard as if it
had flash, without paying mana costs.
If it lands on tails, the chosen player may cast an instant or sorcery from your graveyard as if it had flash, without paying mana costs.
