The One Reborn

Menace, Trample

For every two cards put into a graveyard this turn, The One Reborn gets +1/+1 until end of turn. Whenever The One Reborn deals combat damage to a player, that player mills X cards. If a Great One is milled this way, shuffle it back into its owner's library.

If The One Reborn is in your graveyard, you may pay its mana cost to return it to the battlefield. It enters with a +1/-1 counter on it for each time it has been summoned this way.
