The end result
To pursue its endgame, the deck should include lots of Auras to fuel Eriette's life drain, and failing that, the deck should use Sigil of the Empty Throne to make and attack with lots of 4/4 flying Angels as a plan B
Its a solid 4/4 that can convert life into clues, and its a nice fit for decks aiming to exploit lifegain/life drain, or EDH decks like Teysa, Opulent Oligarch, which benefit from life loss and clues
Youre already running the expensive half of this combo in your command zone, why not toss the other half in the 98
But above all else, costing one mana means this Rite breaks the fundamental rules of Modern
This card, Blood Pact, would benefit a deck that focuses on aggressive strategies and wants to apply pressure on the opponent's life total while maintaining card advantage
