Flying
When Tetravus comes into play, put three +1/+1 counters on it.
During your upkeep, you may move each of these counters on or off of Tetravus, regardless of who controls them. Counters that are removed become Tetravite tokens. Treat these tokens as 1/1 artifact creatures with flying. These creatures cannot have enchantment played on them and do not share any enchantments on Tetravus.

Such creatures may not have enchantments cast on them, and they do not share any enchantments on Tetravus.
