Hi_diddly_ho_neighbor on Any seats left on the bandwagon?

Thanks DVLuca. Cavern Harpy does seem interesting with a lot of ETB effects and Cloudstone Curio is always a powerhouse. I'll give them a shot.

Hi Hi_diddly_ho_neighbor, a few day ago I've seen a game with Muldrotha, the Gravetide and I can assicure you that Cavern Harpy do her gorgeus things. For the rest, Phyrexian Metamorph may change into Stunt Double, it doesnt copy artifact but the flash is realy attractive. I generaly love to take the max value from every build and I think Cloudstone Curio is well fitted here and I adore the fact that it doesnt target.... But Sylvan Library?? joke aside, I like the building and Pernicious Deed.....I dont know how much I love this card..... +1 for me!

in my experience AEtherling and Cavern Harpy is enough. One of those are first target for a cage counter. Cards like entomb and buried alive are very handy. You dont want to overload your deck with the same effects. Mairsil mostly needs one of them

If you're still looking for cuts here are my suggestions.

Overall Ideas: 1. Cut the instants and sorceries. 2. Add better creatures/artifacts with activated abilities.


I would look to add more wheel effects to get cards into the graveyard. Although it can feel a little similar to chaos the results are more effective card draw and will fill up your graveyard faster with more additions. Meaning you would fill your graveyard with more potential options for Marsil; and will add more overall card draw potential than the following cards: Probe, Flux, Mystical Teachings, Cathartic Reunion, Careful Study, Gifts Ungiven, Thirst for Knowledge, Frantic Search

Silumgar's Command: There are better creatures/artifacts that can fulfill this role through Marsil and have the additional benefit of being repeatable.

Walking Ballista: 4 mana for a +1/+1 counter is not efficient enough to justify it's inclusion.

Argent Sphinx: I think that relying on Metalcraft in this deck will end poorly in most situations.

Snapcaster Mage: By removing the instants and socrceries Snappy becomes less effective and should be removed.

Galecaster Colossus: Similar situation with this card having no activated abilities, the high CMC, and the ability to only bounce two (with the Colossus and Marsil on the battlefield) non-land permanents a turn doesn't seem worthy of an inclusion.

Decree of Pain: Being in Grixis colors, you have access to more effective card draw and board wipe spells than to justify this cards high CMC even with the cycling component.

Anthroplasm: This card confuses me and I don't understand its use. Care to enlighten me?

Cephalid Coliseum: You have access to better card draw that is repeatable.

Hammer of Purphoros: Unnecessary haste inclusion.


Basalt Monolith: All the ramp. None of the draw backs.

Hateflayer: BOOM, goes the dynamite.

Pili-Pala: The best part of your deck is this card.....

Jace's Archivist: Wheels for days..

Avatar of Woe: Problem solved. Plus can be a cheap cast on its own.

Urborg, Tomb of Yawgmoth+ Cabal Coffers: Need I say more?

Chromatic Lantern, Commander's Sphere, and Fellwar Stone: Three color deck has three colors...

Vandalblast: You're playing red right?

Mercurial Chemister: Ehh, Idk about this one.

Entomb: Tutor time.

Gamble: Great tutor for your deck.

Cavern Harpy: Wow, just, wow....

Training Grounds: Mana reductions are the key.

I'd cut all the Ordeals except for the green and blue ones. Dealing 3 damage, gaining 10 life o discard someone two cards is not as good as drawing or ramping two lands. Now you can also remove the creatures with heroism.
You can also swap Forced Adaptation for Ring of Kalonia or any other of those five rings or Blade of the Bloodchief.
Hardened Scales and Winding Constrictor are no brainers.
Also Hadana's Climb and Cathars' Crusade are bananas.
Give / Take an amazing drawing spell.
Gilder Bairn improved Vorel that can also double counters on planeswalkers.
If you can afford a Kalonian Hydra, a powerhouse here.
With Cavern Harpy, Horned Kavu, Fleetfoot Panther or similar creatures and Ramos you can produce a ton of counters and mana, if you have two of different colors your can go infinite. It's a good idea here to use creatures with two or more colors to get more counters from Ramos.

found this deck as i always use your meren deck for reference.

Another Aluren combo would be Blood Artist + Endless Cockroaches if you had a sac outlet.Blood Artist could also help with the Cavern Harpy combo too, as you would be hitting the whole table, not just one person.

Big fan of this deck, will be stalking it for ideas im sure!

Thanks simplebricks for your comment and recommandations.

I added a Mortuary Mire and 4 Ash Barrens to improve my land base. It helped a lot with the deck consistency.

I added a Undying Evil. I don't know yet if I like it.

With this deck, it is suprinsing easy to keep your hand full, thanks to Cavern Harpy So far, I have trouble against most of top tier decks...

Have you tried it? Thanks again for your comments!
