Treyan, Keeper of the Unwilled

Indestructible
When this creature enters the battlefield, it gains
all activated abilities of all creatures on the
battlefield. You may spend mana as though it
were any color to activate any activated abilities
gained this way.
Whenever you activate an ability gained this way,
destroy the creature in which the activated ability
was gained from.
"Monsters user their instincts to slaughter. I suppose I
use their instincts as well." - Treyan
