Finks vs Thragtusk is idk, Timely probably just better than Finks and if desperate for life Thragtusk is a better hit on Rites obviously

Surgical is pretty much a garbage card in the meta so it should probably be a Purge or Self-Inflicted Wound to help deal with Rhino.  Purge gives another out to Blood Moon obviously but I think the decks biggest weakness is pretty much just losing a million life to Rhino and burn spells.

Iona answers Burn, Tribal Zoo decks still a nightmare.  Empyrial Archangel sorta works against them but still pretty useless against Rhino due to life loss.

2 Duress probably unnecessary with 7 discard spells main + 1 Despise in the board, can probably move down to 1 and open up some space for the Archangel?

Stony Silence is also pretty terrible, very narrow card that doesn't offer much versatility, especially since it's hard to recur.  Golgari Charm is good enough vs Affinity most of the time anyways, and sometimes Stony Silence does nothing against Tron when they cast Wurmcoil and Karn off Tron pieces, but that's not usually a worry-some matchup anyways.

Self-Inflicted Wound also presents the option of answering Geist and Colonnades.

Esper Charm?  Sylvan Caryatid?  Wall of Omens?

Pact pretty much only seems relevant as a surprise card vs Twin - inconsistent vs Junk Midrange decks and any other deck that can present Rhino as a threat.  Probably not useful, all things considered.  Potentially replacing with a 4th copy of Abrupt Decay.

-1 Inquisition -1 Thoughtseize -1 ??? +3 Sylvan Caryatid
-1 Eternal Witness main, move Thragtusk main, +1 sideboard card?
