Marchesa Modular (EDH / Commander)

[12-24-2022] Moved to moxfield: see https://www.moxfield.com/decks/jmekDbj6N0-2JcGouCNNcw for an updated list.

Create a near-unstoppable engine with Marchesa, the Black Rose, a sac outlet and modular creatures to gradually grow your artifact force, ping people down with Flayer of the Hatebound, Scuttling Doom Engine or Goblin Bombardment (or Marionette Master if you find a spot for it) and outvalue your opponents.

Combo's:

• Ashnod's Altar + Flayer of the Hatebound + Sage of Fables (sac Flayer, remove counter and draw a card when it comes back with mana from Altar, repeat)
• Ashnod's Altar / Goblin Bombardment + Metallic Mimic naming Beast + River Kelpie (drawing is not optional, so danger of decking yourself)
• Marchesa, the Black Rose + Time Sieve + 5 artifacts that recur themselves (Did anyone say Myr Battlesphere?)

Notable interactions:

• Sage of Fables + Metallic Mimic naming Wizard will add a counter on Metallic Mimic. (However this does not apply for Duplicant, because it only gets the creature type after the triggered ability resolved, at which point it had already entered the battlefield.)

Weaknesses:
Graveyard hate, bad at removing non-creature permanents
Could use some better finishers (Wurmcoil Engine, Kappa Cannoneer)

Possible swaps:

• Price of Fame → Lethal Scheme: potentially free removal and instant speed counters on our convoking creatures (budget alternative: Astarion's Thirst)
• Harvester of Souls (or Demonic Tutor for a little more variance in play) → Clan Crafter: way more in line with the flavor of the deck
• Grave Pact → Dictate of Erebos: extra mana but one black pip less, which makes it a lot easier to cast in a 3-color deck
• Find room for Arcbound Whelp in case we want more modular effects (flying and firebreathing makes it a better option compared to Arcbound Hybrid/Arcbound Slasher and maybe Arcbound Tracker)
• Ornithopter of Paradise: ramp and fixing on an artifact creature, appears way better than the Myr (can even become a threat with it's evasive flying ability should it accumulate enough counters)
• Inventors' fair, Tyrite Sanctum: we just have to be careful not to add too many sources that produce colorless mana
• Mystic Forge could be a nice card advantage engine with our 40+ artifacts in the deck (however you can't play artifact lands with it)
• Fit in Counterspell, but it's so hard to make cuts...

Current sidegrades being tested (because I needed the original cards for my Olivia, Crimson Bride deck):

• Talisman of Indulgence → Ornithopter of Paradise
• Whispersilk Cloak → Clan Crafter
