Hey Profet93, thanks so much for the view and suggestions

Jet Medallion I originally had in deck, but found that the ramp didn’t help in my commander, and quite a few of the spells I play over and over don’t have any colorless costs, so I swapped it out for Bontu's Monument, which had the bonus of doubling my commanders ability.

Bubbling Muck – I don’t love the one-time use of it. Would take the space of something that I can use again and again in this deck.

Cabal Stronghold – I think this is a carryover from before I had a coffers. I could easily swap it out for Urborg, Tomb of Yawgmoth. I actually have one sitting in a binder not getting used.

Nykthos, Shrine to Nyx – Of all the lands, this is the one I like the most. I checked and there isn’t one in my binder, but I do have sitting in a for-fun The Colossal Dreadmaw deck. Would probably swap out Castle Locthwain. The draw is nice but find I don’t generally need it.

Deserted Temple is ok, but I don’t have mana doublers and other than coffers (and I guess now Nythos there isn’t really anything I need to untap.

Thespian's Stage and Vesuva – I am not a huge fan of the copy lands, V in particular enters tapped, which I hate. And they are both dependent on me having something that is worth copying, which isn’t always the case.

Contamination – If I had a different playgroup, this would be an automatic add, but my friend group doesn’t love playing mass land hate. A Strip Mine is fine, but something that shuts down another player completely, we generally don’t play just to keep everyone having fun. Infernal Darkness is kinda the same thing, so going to pass.

Imp's Mischief I just checked, and I do not own one, but am going to have to add it to my next buy list. Mono-coloured decks have some real blind spots and having a quazi-counter available would be great.

Skullclamp is going to go on a sidelist for this deck for a while. My mono-red Purphy relies on it for draw, but so far with Ayara hasn’t really needed the extra draw very much.

Carnival of Souls – I did have this one in an early build of this deck, but with my wincon being Plague of Vermin this wouldn’t work, and I feel like in a 4-player game I am going to lose more life than I can afford.

Thanks again for the suggestions. I have already added the two lands.
