vampire mtg commander deck Edgar Markov Tech Rally your forces Vampire Token // Vampire Demon

Alternative Virtue of Loyalty builds which found traction over the weekend include a UW tokens build that pairs it with Regal Bunnicorn and Invasion of New Phyrexia: Theres also this sweet white/black deck list: Virtue of Loyalty seems at its best when your creature deck is able to drag out games, and the lifegain package of Gumdrop Poisoner and Phyrexian Missionary certainly offers that

On the commander only list, I place a bigger emphasis on how well they support various archetypes

Equip Helm to Celebrant, make a new Celebrant on combat, attack and exert it, then repeat the process during your extra combat

Overall, Animate Dead is a great card in a lot of black decks simply because it can give you double the value for your creatures, as well as your removal spells

Individually these effects are marginal: but combined they form a card that was so good, many non-red blue base decks started playing red just to get it (plus Flametongue Kavu, to be perfectly fair)
