Another similar, creature sacrificing combo is:
Verdant Succession + Nantuko Tracer + (Something to abuse sacrificing creatures to, like Husk, Altar, or bombardment).
Another oldy but goody infinite mana combo is either High Tide, if you're playing mono-blue, or Mana Flare if you're playing red/blue, and then cast Palinchron. Bounce the Palinchron around for infinite mana, then Rolling Thunder/Fireball/Ambassador Laquatus everybody else out of the game.
Oh, and it's not an infinite mana combo, but a massive mana combo is Mana Flare and Candelabra of Tawnos
ALSO, an interesting card to run with any infinite mana combo, (Provided you can get blue mana off it), is Compulsion, (Or that similar card from the Urza's Cycle). You get your 3 trillion mana, then just Compulsion your way to a hand full of counterspells and your kill card. An added strategy is to keep a couple big card drawers in your deck like Opportunity so you can get your hand size bigger, that way you can Compulsion to whatever kind of hand you want, and then just win the game with it.
