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
A threat/value-engine like Fable being this prevalent could be a problem, but the metagames seems to have adapted to survive it
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)
I, of course, had other ideas
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
That should happen within the first few weeks, I think
