@wfain I was thinking about trimming colors also, but am more interested in getting rid of red. the splash is pretty light and seems mostly replaceable. Anger has been okay at rebuilding against control decks and in theory is a way to battle oath decks, but in practice it might not come up enough to be justified. Against control they can often interact with the GY with deathrite or rest in peace, or you just don't need that effect too much. Against oath you're probably just going to lose to a resolved Oath regardless and i'm more willing than most to just kinda punt that matchup.
the benefit of going without red would be that you have more stable mana against wastelands, easier decisions fetching, and another utility slot in the deck. I'd like to fit in another fast mana (spirit guide 2 most likely) and lean on kambal and thalia harder.
that RUG list looks real spicy though! lumberjack is a sweet card and is that edric hiding in the corner?? love it! I am real interested in hearing about all those 1-ofs and how they perform after more matches. Dack, Ooze, Scryb ranger, green sun all are real interesting. My fear is that giving up on the hatebears is going to really cost you against PO which seems to be everywhere.
