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 :)

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.

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.

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!

Horseshoe Crab , Vigean Graftmage , Pili-Pala , Simic Ragworm , Knacksaw Clique , and Soliton are a bunch of untap effects you can run. Combine them with anything that produces multiple mana, Gyre Sage , Karametra's Acolyte , Argothian Elder , Marwyn, the Nurturer , Viridian Joiner , Incubation Druid , Gyre Engineer , or Elvish Aberration and you have infinite mana.

With infinite mana, cards like Cytoplast Manipulator look better. Infinite mana also means infinite untaps, so Sage of Hours got better, too.

Hey there. Working on my own Mairsil build and have been using your build as inspiration and a reference point since Mair is a completely different type of build than any other Commander. I have some questions about your build and statements about my own that I hope you can provide some insights on as I haven't piloted Mairsil yet.

How does Mairsil's ability to run on board removal like Avater of Woe and the Disk effect your need to run wipes and removal in the deck? I'm running 5 Crawlspace like effects including Silent Arbiter and Caverns of Despair and was thinking along with the disk maybe I wouldn't have to run board wipes because of it. Or is the fact that often your board state will just be Mairsil and some mana rocks offset this and create a need for the same or more wipes as most decks?

It seems to me that you would want to be untapping Mairsil as often as possible. Would you suggest running Horseshoe Crab on top of School and Morphling?

I was thinking of running Traumatize to play on myself thus giving me instant access to have my deck to cage. Thoughts?

Also considering Archeomancer to recur Buried Alive and Entomb (also, let me recommend Final Parting ) or is this unneccessary over kill?

I loved your red and blue deck, I made my own based on yours with very few changes. I think for this deck you should consider Horseshoe Crab because it already combos well with Hermetic Study and Psionic Gift even though the combo isn't infinite, it gives you a little bit more options. But I don't know what you would replace! Herbal Poultice is awesome, but I think Lotus Petal is better than Bone Saw but it raises the price, so I guess not if you don't already have some around. Love your decks!
