Well, the first thing I noticed was that you have Marchesa, the Black Rose listed as a creature, so please do remove that.

My own suggestions to remove.

1. Dack Fayden = doesn't do much in a Dethrone deck (IMO)
2. Keiga, the Tide Star
3. Kheru Bloodsucker
4. Liliana, Heretical Healer
5. Predator Dragon
6. Pawn of Ulamog
7. Molten Primordial
8. Oona's Blackguard
9. Perilous Myr
10. Crosis, the Purger
11. Chasm Skulker
12. Bringer of the Red Dawn

in my opinion, you'll have to find a right way to play Marchesa. I've seen a lot of version on Marchesa here itself and I feel that you don't have the right way of playing it.

You can choose to either do the following:

1. Play for its color (disruption and chaos)

2. Play for the ability (dethrone)

rustyknives thanks man, that helps a lot.

some of those i can definitely get rid of, but they are all useful in this deck, how do you decide??

and also i am playing for the abilities of marchesa, not only the dethrone but also the "when creatures you control with +1/+1 counters die" effectplus the added bonus of stealing and then keeping other players creatures.

i thought i was doing a really good job of playing for ability lol

there's 3 main builds for marchesa:1. persist and undying2. I'm just gonna take your creatures.. permanently3. Infinite sac outlet

Usually people pick 2. IMO:Signet>keyrunegilded lotus> spectral spotlightsun quan lord of wu ensures hit if thats a problem

To remove:Kheru Bloodsucker

more help on the way later

Thanks chaosumbreon87 i really appreciate your help!if you can link your cards like Kheru Bloodsucker that helps a lot cause i'm not as familiar with all the mtg cards as i'd like to be :)

rustyknives also suggested i remove Kheru Bloodsucker but i'm curious as to why? it seems to have synergy with all aspects of Marchesa and her abilities.

look forward to more tips haha

Hate to break it to you, but Bringer of the Red Dawn can't be played in here because it has a color identity of a 5 color card. Since the cost isn't in a reminder text like Crypt Ghast's extort ability, it can only be played in a 5 color deck.

Kheru Bloodsucker's second ability is not good as a sac outlet and the first ability is inefficient for draining. Sanguine Bond and Exquisite Blood are the usual win for infinite damage. Also sorry i'll try to link the cards. Blood Moon gets opponents mad if they're running multicolor generals. Bident of Thassa and Coastal Piracy might help draw power if that's a problem.

Acquire and Treachery are also fun "im just gonna take these" cards too

SirFowler cheers, i know that rule i just completely ignored the 5 colour identity haha, thanks for bringing that up!

chaosumbreon87 i dont need Kheru Bloodsucker's first ability for life drain specifically, it's just for taking advantage of my creatures being sacked, and second ability is not the best sac outlet but it works if there's nothing else and it also puts a counter on it. i get that neither of its abilities are amazing, but its better than putting two cards in for an infinite combo that doesnt follow the theme of my deck. that's my thinking behind it anyway, but i will consider taking it out.

oh if you needed single card sac outlets, Viscera Seer is a great one. If you need an ability that gives +1/+1 then consider Carrion Feeder or Flesh Carver. Altar of Dementia could also be used as a sac outlet or win condition if you get an infinite loop started

chaosumbreon87 i already have Carrion Feeder i think there are better ones than Viscera Seer though... i have 8 good and low/no costing sac outlets, you reckon that's enough?

I may be missing something but what is your target/purpose of Bazaar Trader?

chaosumbreon87 Temp steal creatures with cards like Insurrection, Mark of Mutiny ect and use Bazaar Trader to give myself permanent control of creatures i would otherwise need to give back at the end of turn, much like sacrificing a stolen creature with a +1/+1 counter and returning it to my control permanently with commanders last ability.

aah ok. Id choose Chaos Warp over him mainly for some interactive power but i see where you're going with him. Also warning for Grave Betrayal, don't ever cast when there's a Phage the Untouchable at the table Otherwise it should be fine

littlered one of the reasons to remove Kheru Bloodsucker was the it doesn't really do much other than causing an opponent to lose life and you gaining life. And to sac creatures just to give itself a +1/+1 seems a little... off... if you know what I mean.

I do like the idea of your deck right now and if I were you, to be really on the offensive side, I rather have Sheoldred, Whispering One and probably still remove Molten Primordial.

The versions of Marchesa, the Black Rose that I have seen, uses creatures such as Mikaeus, the Unhallowed, Sheoldred, Whispering One, and other "enter the battlefield" or "leave the battlefield" or "during your upkeep" effects to keep the opponents board presence in check, e.g. must always be left with either one or no creatures for you to dethrone. One of the other cards they will play is probably Scourge of the Throne to give themselves an additional attack phase.

What you can do also is to have other sorcery like Relentless Assault, or Final Fortune (if you are desperate enough) or Aggravated Assault. Just my 2 cents.

chaosumbreon87 i honestly have no clue what Chaos Warp has to do with anything... it's not even close to a replacement of Bazaar Trader lets me keep stolen creatures. Chaos Warp is literally just removal and nothing more, i'm very confused by this comment, soz :/

rustyknives causes EACH opponent to loose 2 life, but yes, i know what you mean.

Sheoldred, Whispering One and Scourge of the Throne are both cards i definitely need to get, but so expensive :(

And Molten Primordial really just seems perfect for this deck, it's a 2 for one card, big creature with haste, plus a Mass Mutiny for only 2 extra mana! that's epic!Please explain your reasoning for why i should take this card out, i am genuinely curious :)

I do however like Aggravated Assault and may well get myself one if i can trade for it!

littlered: I think it's just a personal opinion about Molten Primordial that I don't like how it works. I would actually prefer Insurrection over that as the main idea is to get all the creatures with +1/+1 then have a way to say each of them and at the end step, it comes back on your side of the board, rather than on theirs. I tend to build decks to be slightly greedy. There are other options as well, eg Kiki-Jiki, Mirror Breaker + Zealous Conscripts or Splinter Twin + Strionic Resonator + Zealous Conscripts or other combos.

If you are unable to get Sheoldred, Whispering One, you could try by getting either the following:1. Fleshbag Marauder 2. Merciless Executioner

These works well with Mikaeus, the Unhallowed

rustyknives but i also have Insurrection (why not have both?) also i prefer stealing (Act of Treason style) over creating (Splinter Twin style) as it both removes a creature from them and gains me a creature.

Also i already had Fleshbag Marauder and Mikaeus, the Unhallowed and Zealous Conscripts

Chaos Warp may not be a suitable replacement but it comes in handy for getting Ghostly Prison/Propaganda/win combos off the board

chaosumbreon87 good point, sorry i just got really confused cause i thought you were comparing it to Bazaar Trader lolit's not a bad suggestion, i do need some non creature removal, that's for sure!

littlered: As mentioned, I'm greedy in a sense that I prefer to cover my own board than theirs.

Have you physically tested the deck with the new modifications? I think it would be a good way to see if the curve of the deck flows properly and that you're not stuck holding cards too long in your hands.

Maybe you can also play with Vicious Shadows. Whenever a creature leaves play, you deal damage equals to the number of cards in target player's hand. It can be bitchy, though.

I might also want to suggest that you play with Umbral Mantle. Just for the untap purpose. I think this will work well with Bazaar Trader. Just saying.

Warning, land hate may be in order also. Homeward Path screws plans heavily

chaosumbreon87: Not unless the dethrone is in place. That's what I think.

by homeward path's wording even if you have dethrone, sac them and revive them, all creatures return to normal owners

rustyknives i like the look of Umbral Mantle do you know of any other cards that let me untap creatures repeatedly?

chaosumbreon87 yes, all decks have their weaknesses, Homeward Path is probably my decks biggest... might throw in some Encroaching Wastes or Ghost Quarter to deal with that.

I also need some mass enchantment/artifact removal... you guys got any ideas for that?

Btw thanks both of you, getting lots of good ideas from you two haha :)
