Saruman, the White

Realm Lord — If you control Orthanc, at your upkeep you can exile this Saruman and transform it into any other version of him.

Hexproof. Defender. If Bree, Helm's Deep or
Edoras become destroyed, you gain control of them with 1 loyalty counter.

If Saruman goes to the graveyard, instead transform it into Sharkey.
