T1 all the colored mana you could want

[Pi]

Swamp into {dark ritual} into 3 more rituals. {9} into {composite golem} and {nim deathmantle}. Sac the golem for {W}{U}{B}{R}{G}, pick your favorite color of mana to save, and spend the other {4} to bring back your golem. The only thing stopping you from winning T1, is that this combo just took all 7 cards out of your hand.
Edit: make sure to use capital letters, when using mana symbols

And have a deck composed of this and three {door to nothingness}. T3 wins

Less epic, but all for effect. Would work too, and make it a turn 1. If only you could have 8-card decks
