Gen, Confider of Ages

Mana cost: {W}{U}{B}{R}{G}

Legendary Creature — Human Wizard

Gen gets +1/+1 for each different year of release among other nontoken permanents you control. (For example, if a card was released in 1993, that's one year of release. Specific editions matter.) Whenever Gen attacks, if its power is 30 or greater, you win the game.
