Metaion the timelord

Haste, Protection from everything
You may cast this card from your hand without
paying its mana cost if you control no creatures. Whenever Metaion deals combat damage to a
player, return all other creatures to their owners
hands. Metaion deals 1 damage each opponent for
each creature returned to the hand this way.
Shuffle Metaion into your library at
the beginning of your upkeep.
