Ultima is relevant for a few key reasons, the main one being it destroys your opponent's copies of Cori-Steel Cutter

Sorin comes loaded with three abilities, one that lets you pick off little creatures while fueling your life gain, and tremendously powerful ability to set your opponents life total to 10, and then a mesmerizing ability to gain control of an opponents turn

Grindy creatures that offer immediate and extended value thrive in that format, and this looks like an all-star for black decks

Summon: Fenrir might only be temporary, but you can get your free land and then trade off this saga creature for value, effectively giving you an easy two-for-one
