name: Tetravus
originalText: Flying
  Tetravus gets three +1/+1 counters when cast. During your upkeep, you may move each of these counters on or off Tetravus.  Counters moved off of Tetravus become independent 1/1 flying artifact creatures.  If such a creature dies, the counter is removed from play.  Such creatures may not have enchantments cast on them, and they do not share any enchantments on Tetravus.
