Mindgorger Wren

When Mindgorger Wren dies, you may search
your library for a card named Ashiok Rended,
put it into your hand, and shuffle your library.
Whenever you cast a planeswalker spell named
Ashiok Rended, if it resolves, you may return Mindgorger Wren from your graveyard to the battlefield.
