AEtherling Discussion

Jackfrost23 on WhAT, BUdGET ConTROL? (Esper Control Ft. Snow)

Thanks for the feedback The_Legionarre! I added the AEtherling and the extra gearhulk as well as two Drown in the Loch (I've on the fence about that card for a while). I play a full four Opt and don't think I need anymore cantrips

I'd cut the tar pits and just add in more collonades, also I'd play 2 dead of winter (which you are) with 3 unconditional wraths, just so that you can 2 for 1 against tron or something. Also i'd go up to 3 gearhulk, and replace dream crawlers with a single AEtherling and an Elspeth, Sun's Champion. Aetherling requires you to keep mana up, but you should have lots of mana since you're not playing fetches. Also it allows you to speed up your clock and it dodges edicts and wrath effects, something the crawler doesn't do, meaning that as long as you're smart your aetherling can stay alive for ever. Elspeth pulls double duty as a conditional wrath as well as a win con with her plus, providing you huge amounts of blockers as well as swarming opponents, letting you stabilize against most decks on her own.

In terms of more objective changes you should make, add drown in the loch, its insane. add a playset of cantrips, Thought Scour has good synergies with Drown in the Loch as well as Into the Story which is a nice card advantage spell you might want to try. Serum Visions or Opt should work well though in a vacuum. Also take out the inquisitions.

I love taking a pile of cards and seeing what you can turn it into! I don't know which cards you have or what budget you have for acquiring new ones, but I'll list some cheap suggestions I have for a variety of archetypes you could pursue.

1) Simic ramp: Already goes well with Air Elemental, Archetype of Endurance, Oakgnarl Warrior, Overgrown Battlement, Yavimaya Wurm, Simic Keyrune. Some inclusions might be Llanowar Elves, Axebane Guardian, Coiling Oracle, Maraleaf Pixie, Beanstalk Giant, Terra Stomper, Lorthos, the Tidemaker. The goal is to accelerate into big threats.

2) U/G unblockable: Already goes well with Marang River Prowler, Downpour, Giant Growth, Might of the Masses, Aqueous Form, Coastal Piracy, Turntimber Grove. Some inclusions might be Curious Obsession, Daring Saboteur, Mist-Syndicate Naga, Ohran Viper, Trygon Predator, Distortion Strike. The goal is to get value from hitting with unblocked creatures.

3) U/G tempo/control: Already goes well with Breaching Hippocamp, Cloaked Siren, Mist Raven, Fog, Negate, Unsummon, Voyage's End, Claustrophobia. Some inclusions might be Vapor Snag, Dissolve, Mana Leak, AEtherling, Delver of Secrets  Flip, Devastation Tide. The goal is to deny the opponent their things while playing tricky threats of your own.

I also see cards in here that could work with mono green Assault Formation, simic +1/+1 synergy, or flying tribal, so you have a lot of options. As a sidenote, I'd also recommend upping your land count to about 24 while you have so many 5+ cost cards in the deck. Anyway, good luck!

Tylord2894 on Mairsil ETB

3 months ago

There's one interaction about Mairsil that isn't directly tired to your question but is useful to know if you're making a deck around him.

The second ability of Mairsil restricts you that you can only use each ability of the "caged" cards only once per turn. If you activate an ability of Mairsil and then Mairsil is blinked, you can activate that ability again that turn. This is because that single-use restriction applies to the "Mairsil" game object that used an ability. When Mairsil is blinked, you now have a new "Mairsil" object, so the new object doesn't have that restriction applied yet.

A common combo with Mairsil is AEtherling. With any ETB or "free" ability, you get massive (or infinite) value.

I tried creatures like Aetherling too. However i never liked mutating onto them for two reasons. First, they are way too expensive. I want my mutate targets to cost less than the mutate creature so that I play them first and maybe mutate immediatly afterwards. Since all the power and toughness expensive creatures like Aetherling prove are useless anyway. Second they dont really protect my mutate pile. Flickering or undying put all creatures back seperatly. I really do not like that. This is mostly the same as loosing the pile entirely. Having hexproof or indestructible on the mutate target is for much better since its completetly protected except for boardwipes when using hexproof.

I suggest that you put in Gladecover Scout as well as Elusive Tormentor  Flip and cut AEtherling as well as Endling.

You are only playing 9 Muatets creatures too. That seems to be too low for a mutate forcused deck. I would play atleast 15. You got enough mutate targets anyway so I would suggest cutting a few of those since these creature are worthless in multiples.

Exil3dbyrd on Mairsil, Pretend to be Competitive v2

My first version ( included Nevinyrral's Disk and AEtherling. It was much more commander focused. Overall I would say the first version plays better in most pods but this version will be much better in a cEDH pod.

Netherborn Altar is a bit silly. I'll definitely enjoy the card and think it will end up in most of my decks. I write about it here because I think this is where it has the weirdest potential.

First is the simple Hex Parasite interaction. Mairsil effectively costs 6 mana forever with these 2 working together and I lose no life. Not amazing. Won't even come up in most games. Potentially saves my bacon every now and then though by making Mairsil castable after he has real deathed 4 or 5 + times.

Silly interaction comes from the altar being in the cage. I'll need a way to kill Mairsil but it goes like this.

Murder goes on the stack, Netherbon Altar from cage on stack, Sacrifice Mairsil on stack.

Sacrifice resolves, Mairsil goes to command zone, Altar resolves Mairsil goes to hand, Murder has no target.

I'm NOT 100% sure about this interaction until all the official rulings are made. It should work because the Altar does not target the commander it simply specifies the commander. This interaction is not as strong as say AEtherling in response to murder but another layer of protection for Mairsil shenanigans is always great.

foxboy93 so many words! lol, kidding. When I first made the deck it was very artifact focused but over time I've lost a lot of that. Argent Sphinx sadly became very difficult to activate... Sanctum of Eternity actually is a decent inclusion since it is just a utility land. I still have a decent amount of room for those. Retrofitter is something I've wanted to include more of. That is abilities that make tokens. Given that Mairsil locks up most of my creatures Oona has been very helpful even when I'm not winning off of her. Prognostic Sphinx is interesting... I'll think on that one. Planar Bridge came out not too long ago. Very silly when I get a lot or even infinite mana going on but otherwise just really hard to make useful. I forget what replaced it.

I've also very much enjoyed doing things on everyone's turn. Haste has been such a great effect to have to help enable that. Anger and until recently Fervor were key pieces of my deck alongside AEtherling and other blink effects. I haven't gotten to test the change but I replaced Fervor with Purphoros, Bronze-Blooded. I'm really interested in seeing if I can take much advantage of his activated ability but he is really just here as an indestructible source of haste.
