Triumph of Twilight

(Battles can be cast only if each player controls four
or more creatures.)
Turn each face down card you control face up,
then put a +1/+1 counter onto each elf creature
you control. Those creatures gain vigilance, and
hexproof until end of turn.
"And the eastern host of the Orcs was taken between
the armies of the Eldar...and were utterly defeated."
