Maybe Im just too much a sucker for powerful synergies, but flooding the board with tokens early to get paid off by either Jeskai Ascendancy or Howl of the Horde into Stoke the Flames (with an honorable mention to Obelisk of Urd that sadly will only buff one type of token) a turn or two later sounds like something that should easily have enough raw power to hang with other Standard decks
