The List

Phyrexia: All Will Be One

Enchant basic land you control
When Ossification enters the battlefield, exile target creature or planeswalker an opponent controls until Ossification leaves the battlefield.

Auras attached to the exiled permanent will be put into their owners' graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist. When the card returns to the battlefield, it will be a new object with no connection to the card that was exiled.

If Ossification leaves the battlefield before its triggered ability resolves, the target permanent won't be exiled.

If a token is exiled this way, it will cease to exist and won't return to the battlefield.
