Night Flyer

Flying
{1}: Night Sight: During the first main phase of your
turn, you may roll a d6 die. If it lands on an odd
number, Night Flyer gets Hidden 1.
Night Flyer gets +1/+0 for every other Giant Bat, but
Night Sight's mana cost goes up by one.
Giant Bats are rare at night, but they should be
killed to harvest the super-calcium molecule in
their bones.
