Dursha, Construct Corrector

If an artifact creature would be put into your graveyard from the battlefield, you may exile it
instead. If you do, exile X cards from the top of
your library, where X is the exiled creature's
power. You may play those cards until the end of
your next turn. This triggers only once per turn.
{t}, Sacrifice an artifact: Create a 1/1 colorless Construct artifact creature token.
