So for Dragon's Maze pre-release sealed, which guild do you think has the best shot of winning?

I know all the spoilers aren't out yet so any discussion is still incomplete until we know the whole set. I've been to the last two pre-release events of this block and I chose my guild based fun and flavor. Golgari, then Dimir if you want to know. Now I want to pick by power, consistency, and content given in a limited scenario. If Dragon's Maze turns out like RTR and GTC I can't help but feel something with white will be the strongest overall.

I want to hear the communities thoughts though. What do you think will be the best guild to pick?
