Red deck wins, or whatever they call it.

As for the deck, add in three more Sakura Tribe Elder; he works great alone, and combo's well with Meloku/Azusa.
You could probably take out the Orochi Leafcaller for the elders, as the elder's alone will fix your color problems, so you don't have to go around tapping green for blue all the time, which you'll still do with the Orochi Sustainer.
If you'r playing for casual or fun, you can leave it the way it is. Genuinine fun is what you got right there.

You might want to join the StarCityGames Message boards, as they have a ton of this stuff.
