Tetravus rulings:
2008-08-01: This card now has two upkeep-triggered abilities. Its controller chooses the order they are put on the stack, and thus the order in which they resolve each upkeep.
2004-10-04: Only Tetravites from this specific Tetravus may be used for the ability. Ones from a different Tetravus can't.
2004-10-04: Any +1/+1 counter which is on this card can be turned into a Tetravite token. It does not care where the +1/+1 counter came from.
2004-10-04: If the Tetravus is destroyed when the Tetravites are off the card, they are not destroyed, they are just orphaned.
