QuirkyQU33FER on Humanity was an Experiment by Aliens

Incubation Druid + Freed from the Real (if druid is adapted) = infintie blue and/or green mana

once you have that here are some of the crazy possibilities you can do with it:

Experiment Kraj + Presence of Gond + Gilder Bairn = infinitely big infinite tokens lol

Experiment Kraj + Knacksaw Clique = exile everyones library

Experiment Kraj + Cytoplast Manipulator + Horseshoe Crab or any untapper = steal everyones shit among other things

DarkHero on Mairsil, The Pretender Things That ...

4 months ago

Doing a little Brewing with Mairsil, the Pretender because I love commanders that let you use cards that don't see a lot of play. I've definitely come across some interesting stuff.

I'd like to share some of the interactions and also inquire about what others are thinking as far as efficiency and fun, or any other combos/interactions not mentioned.

  1. There are ways to get around the "only once per turn" wording. This is probably the most confusing piece of decks based on this Commander. The most obvious choice is Quicksilver Elemental , allowing you to pay to essential get a new instance of an ability. I am lead to believe that flickering Mairsil will also reset this rule. But if this is wrong or there is a way to make it more clear (OR OTHER WAYS TO DO IT) please share.

  2. AEtherling , Torchling , and Morphling are just about mandatory for protection and evasion.

  3. Untap effects are powerful, making Pili-Pala combos a thing, but I'm not sure what makes the most sense here. And finding a home for Horseshoe Crab .

  4. Skill Borrower can basically be a Mairsil Lite

  5. Loot Effects are excellent because Mairsil doesn't care if the target are in hand or in graveyard.

6. Pack Rat can be used to create copies of Mairsil, which one will die, but it can be used to evade and get additional uses of abilities.

7. Vector Asp ...

8. Anthroplasm + Sage of Hours in cages makes for extra turn shenanigans

9. Soul of New Phyrexia + Nevinyrral's Disk in cages creates one sided boardwipes on a stick.

10. The Chain Veil ? Could Grixis Superfriends be a thing with a combo here? If anything you get the ability without the drawback.

11.And this is the big one. Mirror-Mad Phantasm . So the wording here is different, "a card named..." means we won't replace the name with Mairsil, so we will rummage through our deck looking for another Phantasm, that isn't there. So we are able to put our entire library into the graveyard. From here we can use a combo based around Narcomoeba , Bloodghast Fatestitcher , Dread Return , Laboratory Maniac , and flashback Deep Analysis for the win. It's a little janky, but it is essentially a 2 card combo with a little support.

12.Aside from that, Necrotic Ooze would love all these activated abilities in the graveyard.

Again I'm looking to provide some clarity, for others and myself, on good ways to take this commander. If anything I've shared is wrong or there are better ways to do it, please let everyone know!

I don't believe that cards like Horseshoe Crab and Simic Ragworm work with kraj, since they specify the card's name in their rules text.

Awesome! I was building something similar actually and I love to see the use of Arbor Elf with Utopia Sprawl which I didnt consider because I was so fixated on the Horseshoe Crab . Thanks for the inspiration. I will try to mess around with the list and get some testing in :)

LadyZ on All for One (Experiment Kraj)

I'd definitely add Horseshoe Crab , it's a good way to untap Kraj repeatedly. Illusionist's Bracers would help you go infinite more easily, and Rings of Brighthearth is another good option if it's in your price range. And why not throw in Simic Ascendancy for an alternate win con?

Just keep in mind, Kraj only gets activated abilities, so it won't get the ability of Soulblade Djinn for example.

SoleRing on The Pretender's Cage

Ryanh12 the AEtherling is indeed the main way of flickering Mairsil. This is probably a last resort though in the case that the other combos cannot be executed. The main cage target for Mairsil is Mirror-Mad Phantasm to put your entire deck into your graveyard and infinite combo from there.

I used to be running a less combo and more value Mairsil deck if you are interested. It ran creatures like Torchling for additional protection for Mairsil. As well, Shauku, Endbringer was an excellent piece of removal. Additional untappers helped me gain additional value. I thought Soliton and Horseshoe Crab were neat and still have both in foil! Attaining a lock with AEtherling and Nevinyrral's Disk was also quite satisfying.

Cloudius on Bounce Shenanigans, Yay or Nay?

Built a Pauper EDH* deck recently centered around shooting down my opponents and their creatures with my army of gunners:

Lock and Load!

Pauper EDH Cloudius


It is really fun to pilot and has its fair share of successes, both in 1v1 and multiplayer formats.

Here's the question:

Should I add in some Bounce Shenanigans (e.g. Banishing Knack , Retraction Helix ) that synergise well with my untappers like Horseshoe Crab ?

They can turn my untappers into "walking cyclonic rift" and also be used to help save my key creatures from targeted removal. But are they necessary or just "Win More" cards?

Looking to tap on the collective wisdom of the community. Any comments, suggestions, feedback and/or upvotes are welcomed. Thanks!

* Pauper EDH is a format where the Commander can be any uncommon creature (need not be legendary) and the deck comprises of 99 commons.

Lock and Load!

It is really fun to pilot and has its fair share of success, both in 1v1 and multiplayer format.

The mana generating engines usually churn out tons of mana and I'm looking for suggestions for effective mana sinks so that they can be channelled to good use.

The sinks that are currently in the deck include:

Lore Weaver - Really handy as she sits in my command zone and is readily available to net me some card advantage.

Watchful Automaton - Filters the top of our library so we draw into our key cards faster.

Horseshoe Crab et al - Needs to be equip with "weapons" before they can start gunning down opponents.

Look forward to your suggestions and comments please. Upvotes are welcomed too if you like the deck. Cheers!
