Here is an interesting decklist that has performed successfully in the current Star City Games Standard Open in Buffalo, New York (the deck is in the top 4 as of the moment). It takes a route via the tribal Elves but with a twist of White.
The White splash is for Restoration Angels and Village Bell-Ringers which abuses tapping of the mana Elves, in turn generating a huge mana for Genesis Wave. The big guy Craterhoof Behemoth goes in for the one-attack kill.
