Bloodthirsty Shadows

Whenever an Elemental enters the battlefield
under your control, face-down creatures you
control gain augury {1}{b}{r} until end of turn.
( {1}{b}{r}: Turn this card face up, then turn it
face down. Activate this ability only once each turn.)
Whenever a permanent you control is turned
face up, Bloodthirsty Shadows deals 3 damage
to any target.
