Triskaidekaphile (BLC)

Creature — Human Wizard

You have no maximum hand size. At the beginning of your upkeep, if you have exactly thirteen cards in your hand, you win the game. {3}{U}: Draw a card.

Niche win condition for blue control and hand-size strategies, but requires precise setup and is easily disrupted by discard or creature removal before you untap. The activated draw ability is efficient, but the thirteen-card threshold demands dedicated deckbuilding around hand-filling effects—a constraint that limits its appeal to casual and Commander formats where you can afford the deck slots. Better as a fun alternative win condition than a primary strategy.
