MTPW - Celebration (version 2)

I wasn't happy with the Celebration deck I posted earlier. Just too much variance. So I've narrowed it down a bit. This is your basic Creation Ramp decklist that usually goes for heavy-hitting weapons as a finisher. Celebration helps this deck out by giving options for various board states.

If your control is lacking and you're behind on the board, pump up Celebration 12 times to summon a Spirit of Resistance. If you're ahead on the board, 9 seems to be the most reliable spot to amplify to, with only Lavablood Goliath, Zaxo Leviathan, and Clocktower Sentinel to choose from. 6 is mostly reliable as well, but has some duds and a lot more variance.

There are plenty of ramp and plunder options to ensure that you get to 13 mana as quickly as possible, and if your Celebration doesn't come up we can still close out the old-fashioned way with either Diana, Faith's Shield or Massive Greatsword.

MTPW - Celebration is out there if you're into jank. Personally I feel that this list is a little more stable.
