I'll try for a more meaningful post later (on lunch lol). In the meantime, feel free to check out my list for ideas. Narset, American Beauty

Seedborn Muse lets you tutor with Sisay every turn instead of once per round.

Ashnod's Altar is another sac outlet I'd recommend. Like Goblin Bombardment, it enables an infinite damage combo with cards already in your deck. Sac Flayer of the Hatebound to the Altar for . Flayer immediately reenters from undying and hits any target for 5. Use Sage of Fables draw ability with the 2 floating mana to remove Flayers +1+1 counter and draw a card. Rinse and repeat 'til everyone is certifiably deaded.

Nice deck but I do have a few suggestions.

Metallic Mimic and Vigean Graftmage will both protect Marchesa whenever she enters or they allow you to abuse any etb/death trigger on everyone's turn instead of once per round. With Metallic Mimic, sac to rename the creature type and abuse your grossest etb/death trigger and with Vigean, it's 2 free sacs every turn (itself + 1 other). Just have it enter first then graft a counter onto the other creature as it enters. These are both especially gross with Kokusho, the Evening Star and/or Gray Merchant of Asphodel. The lifegain seems counterproductive but trust me, it's not... they will end the game without you worrying about your life total at all.

Spark Double feels like it's a custom made card specifically for Marchesa. Like the above cards, it allows you to abuse any etb/death trigger every turn thanks to that automatic +1+1 counter or you copy Marchesa for double dethrone triggers.

Goblin Bombardment is an excellent free sac outlet here that only 2 colors can reliably deal with. It also enables an infinite damage combo with Glen Elendra and Mikaeus (just alternate Glen Elendra entering from Undying then Persist).

Feel free to check out my list for more ideas. It's one of the top rated Marchesa decks on the site with a big maybeboard and over 180 comments to sift through for insight and more ideas. Upvotes on any of my decks are appreciated. Every Masochist Needs a Marchesa to Love Them

You really should try to drop some of your 4 and 5 drops for 1, 2, and 3 drops (especially the 4 drops since they compete with your commander). Almost 30% of your deck won't come down before Marchesa and after 8 years of playing this commander I've come to realize that what you drop in turns 1, 2, and 3 before Marchesa makes more of an impact on consistency than big flashy cards that come down after.

Assuming you're picking up what I'm putting down, I can help make specific suggestions for both additions and cuts if you'd like.

Davinoth Yeah, the lack of sac outlets was a conscious choice to make the deck fair especially with running Grave Pact, Dictate of Erebos, and Martyr's Bond (other than Yawgmoth at least since he's a draw engine). As far as how cards have worked out... the deck is still in theorycrafting mode and other than goldfishing here on tappedout, hasn't actually been built or played. I want it to be able to win some games but not run away with it and waffle stomp my opponents lol.

I agree that Containment Priest needs to go because it is a total nonbo with my commander and the cards you listed. I'll need to find a replacement (maybe a land like you suggested. Any particular suggestions?).

I still see a lot of destroy boardwipes in my meta is the reason for the redundancy on protection effects like Liesa, Athreos, Broodmoth, and the Flawless Maneuver/Teferi's Protection effects. Athreos is the weakest of the bunch and probably won't make the final cut tbh (Akroma's Will is its replacement I think and I recently picked up a copy).

Phyrexian Arena will probably make it into the deck and will put me up to 10 repeatable draw engines (counting Herald's Horn since I'm so creature heavy). It'd probably replace Solitary Confinement because I'm honestly not sure I have quite enough draw power to reliably sustain it.

Anyways, thank you for getting back to me and if you have any other suggestions, keep 'em coming.

Lmfao... ok, if you say so.

That's fair with Sylvan Library. I run all 9 of the fetches I can along with a few tutors. I shuffle a LOT and this helps me with Sylvan being more selective card draw and digging without being as aggressive by taking 8 just to switch up the topdeck.

I've had pretty good results out of Jared and the monarch mechanic in general. It sucks that you can't become the monarch the turn he enters but once you have it the very next turn, it's easy to hold onto here. He also makes for one hell of a blocker/deterrent for surprise hastey creatures.

I'm with you on Toski/Ohran being my main tutor targets though. I run Imperial Recruiter alongside them for another easy way to Tutor either (or Loyal Apprentice) as well.

Also, have you considered running Kataki, War's Wage? You don't run many artifacts and he's great at taxing and slowing down your opponents.

Nice deck overall but there's 2 types of cards that're underrepresented here... finishers and board protection.

Board Protection: Teferi's Protection, Boros Charm, Flawless Maneuver, Rootborn Defenses, Unbreakable Formation, and Scapegoat (doubles as a finisher with Purphoros out) are all excellent options here depending on your budget. This deck folds like a wet paper towel if you eat a boardwipe and end up in topdeck mode.

Finishers: Shared Animosity and Reconnaissance. Reconnaissance allows you to attack with EVERY creature safely, deal combat damage in most situations, and have every one of those creatures untapped and ready to block/deter attacks by the end of combat. Creatures are considered 'attacking' until the end of combat step ends (you untap during this step as priority passes around the table)

I have 2 main suggestions for you.

First, this deck folds like a wet paper towel to boardwipes. Consider a few cards like Boros Charm, Teferi's Protection, Flawless Maneuver, Rootborn Defenses, Scapegoat, and/or Unbreakable Formation. Protecting your board and avoiding going into topdeck mode make a HUGE difference in this deck.

Second is Reconnaissance. This card allows you to attack with EVERY creature safely, deal combat damage in most situations, and have every one of those creatures untapped and ready to block/deter attacks by the end of combat. Creatures are considered 'attacking' until the end of combat step ends. You untap during that step as priority passes around the table. This also works after first strike damage is dealt but before normal combat damage making combat entirely one-sided with things like Stromkirk Captain/Stensia Masquerade.

Your site switched the playtesting image to full art textless japanese versions of cards even though I have specific versions marked in my actual decklist. How do I switch this back? It's making it impossible to test my deck as I have no idea which card I'm actually looking at. Ty

5.13 avg. cmc is astronomically high even for Animar. Your first few counters are going to be slow and inconsistent.

I'd suggest more low drop creatures like Cloud of Faeries, Destiny Spinner, Shrieking Drake, Dream Stalker, Man-o'-War, Phantasmal Image, Sakura-Tribe Elder, Stratus Dancer, Walking Ballista, Wild Cantor, Imperial Recruiter, Glimpse of Nature, and Utopia Sprawl. I'd also suggest Neoform and Weird Harvest to help look up combo pieces.
