Kai Budde's Wildfire
One of the crowning achievements of Kai Budde's Hall of Fame career was his World Champion title in 1999. He took the top place with this Wildfire deck. The combination of explosive mana accel allowed him to play the game-dominating sorcery post-haste, all the while denying his opponent mana with Mishra's Helix and drawing extra cards via Temporal Aperture. The fact those cards were artifacts then came in handy as Kai utilized Covetous Dragon to beatdown for the win.
