Thief of uncorrupted Souls

When Thief of Souls enters the battlefield
return a red creature or sorcery from your
graveyard to your hand.
Other red or black sorcerys you control cost
{3} less to cast and are indestructible.
The demented souls of tortured and twisted
beings run rampant through these forests
it was only a matter of time before those
poor lost souls started to fight back.
