Drana and Linvala

Flying, Vigilance

{t}, {3}{w}: Prevent all combat damage that would be dealt to and dealt by Angels you control this turn.
If damage is prevented this way gain that much life.
{t}, {p/b}{w/b}{b}, Sacrifice Vampire creature: Draw X cards where X is equal to half of converted mana cost rounded up of sacrificed creature.

Bound by destiny, they bridge the divide, their combined power a force to be reckoned with.
