Snow Creature — Angel 4/5, 4WW (6)
Rare
Flying, vigilance
{T}: When target creature other than Adarkar Valkyrie dies this turn, return that card to the battlefield under your control.
She doesn't escort the dead to the afterlife, but instead raises them to fight and die again.
Illus. Jeremy Jarvis

7/15/2006: Adarkar Valkyrie's ability can target a token creature, but since token creatures cease to exist when they leave the battlefield, it won't be returned to the battlefield.
