Happily Ever After
Oracle Text
When Happily Ever After enters the battlefield, each player gains 5 life and draws a card.
At the beginning of your upkeep, if there are five colors among permanents you control, there are six or more card types among permanents you control and/or cards in your graveyard, and your life total is equal to or greater than your starting life total, you win the game.
As is, it's a somewhat clunky wincon that begs for removal, right after giving opponents a free draw..
