Ravening Chimera

Flying, Deathtouch, Haste, Menace
Deteriorate {4} (any player may pay the deteriorate
cost to exile this card. The card can be played again
from exile, but returns with a -1/-1 counter on it for
each time it has been deteriorated.)
Aggressive, dangerous, and impossible to tame, these loathsome beasts are better left alone.
