Edgar Markov Edgar Markov is the go-to vampire Commander, with the certainly-broken Eminence ability (shared by another one of MTGs best commanders who just missed out on the list, The Ur-Dragon), allowing it to generate endless vampire tokens without ever even being cast and in a way that cant be interacted with
The one big downside of this deck compared to Gruul Prowess is the manabase
That in itself wouldnt be a good incentive to run tokens, but giving your tokens an X/X statline is very significant, and an excellent reason to run Parallel Lives and friends
For just 2 mana, you could turn a Darksteel Citadel into a deadly 5/5 creature
Give this thing trample, flying, or even haste against an unsuspecting board, and you have a card that will defeat opponents quickly and easily
