It also has hexproof from each color for added protection, and annihilator 2 tacked on for good (and thematic) measure
Flash creatures out at the end of their turn, untap, and swing with creatures people didn't think they'd have to block
You can only use this effect of "Witch of the White Forest" once per turn
