While some might argue the original Sorin Markov is the strongest, given its ability to put an opponent to 10 life, its only really great in certain Commander builds
In an open environment (or a closed one in which I had unrestricted creature choice), Id go for Suture Priest early on
Usually Brightstone Ritual will be slightly better, but they can both turn one mana into dozens whenever you need it
Designer Notes: Raise an ever-growing legion of vampires through Edgar Markovs Eminence, unleash your commander, and let the bloodbath begin
Consistency-wise, Glissa, Herald of Predation can take her place in later turns (for token cost rolling)
yeah, this is a great inclusion
