Finished 3-1 last FNM, losing only from the 4-0 player, Mardu DS, in a very close game. Beating G tron, casual goblins and amulet titan. Deck feels much better the more I play it. Aggressive mulligans are a must sometimes, and the london mulligan really helped out.
Torpor orb + sweepers makes sense for sure. Perhaps a 2 orb/1 honor guard split, to play around meddling mage? Same reason for me to board 1 clarion/1 anger. Plus, I think the versatility of the clarion (when in a racing situation for example) might also be worth it. I haven't played with it yet (I only play in paper).
I saw some 5-0 lists recently, running 3x sfm, 1 sofi, 1 skull instead of 1 arbiter, 2 big thalia and some removal or land. Not sure if that's the route though. I recently finished 5-3 during an MCQ, losing to humans, dredge and jund. Titanshift and stoneblade I both faced twice and were real easy matchups.
I'm really starting to like this deck and will continue playing it. This is the list I will run next FNM:
abbot of keral keep vs. heartfire immolator vs. dreadhorde arcanist vs. goblin engineer
assassin's trophy vs. maelstrom pulse vs. abrupt decay vs. pernicious deed
emrakul, the promised end vs. kozilek, butcher of truth vs. blightsteel colossus
karn liberated vs. ugin, the spirit dragon
tithe taker vs. charming prince vs. seasoned hollowblade vs. kor skyfisher
Also:
ajani vengeant vs. nahiri, the harbinger

Every once in a while, similar lists 5-0 on MTGO: https://magic.wizards.com/en/articles/archive/mtgo-standings/modern-league-2019-09-17#mine_- . Maindeck 2 revokers with all the Urza's and planeswalkers around seems interesting. Abrades in the SB might also be better than wear//tears since the enchantment half isn't as relevant that often.
Arbiter + SFM makes sense in lists running vials I think. This deck is too tight on the mana to be able to afford the occasional dis-synergy.
