when they deal or take damage, or activate an
ability, flip them right side up until end of turn,
as long as the card is upside down it has
hexproof and anything on it is hidden.)
Surprise attack (You may tap this creature to
make it fight target creature, this creature can't
attack on your next attack phase.)

cast if you control 3 or more deserts)
