Barrenness

I love this card, and I´m gonna tell you why:

1.- It breaks Govern the Unaligned strategy. Or similar cards that send free pool to younger vampires.
2.- It makes vampires sterile. So they can´t create 1 cap vampires, and embrance it´s useless.
3.- LSJ created "The Horde" to play with them.
4.- Remove 2 blood points, as horseshoes. But this is much better because the vampires can´t fill themselfs another time.
5.- Burn 1 cap vampires.
6.- No cost.
7.- At inferior, it UNTAPS the infernal vampire.
8.- Scourge of the Enochians exists.
9.- You can play it to any Methuselah.
10.- +1 stealth action.
11.- You can´t remove them.
12.- It has burn option.

I don´t like this card, and I gonna tell you why:

1.- It´s rare.
2.- You need a lot of them to play a deck around this card.
3.- It´s useless against allies.
