Is that a copy/paste error in the last UG deck? It doesn't have any fire quanta sources :p Also, I had no idea that UG bypassed SoFr even if you had 4 of them, but I almost never use UG.
And as for getting thumbs ups with arsenic... the best bet might be death mark, animate weapons, and duo it with something weird like life for adrenaline, or stuff like heal or scorpions. Or maybe flying arsenic and SoP/deathstalkers? Or Shard of freedom/flying arsenics! :p I dunno... It's often hard when you have to deal with ten copies of a weapon in your deck; you've just about got to use some animate weapons and then that narrows down what you can do even more. Another possibility could be something like Crusader/flying arsenics; you could do blessings and maybe even shard of patience for beating SoSa; plus, it kinda synergizes with endow, as it will buff the flying arsenic and then endow is based on the modified stats of the weapon. You could do flying arsenics, duo with gravity, and throw in a bunch of black holes and unstoppables and some other control or creatures.
I don't know if any of that stuff will actually get thumbs ups, but it might be worth a try... I'm tempted sometimes when doing arena decks to just roll a dice to determine a duo that I have to make with the card, and see what happens :p
