Maybe you could use Awakening Zone instead of or in addition to From Beyond? Also, check out Elder Deep-Fiend. It kinda functions like a Mistbind Clique which can be a huge tempo swing for you.

And i thank you for the Elder Deep-Fiend idea. Really powerful and budget!

Cards with emerge: Abundant Maw, Decimator of the Provinces, Distended Mindbender, Drownyard Behemoth, Elder Deep-Fiend, It of the Horrid Swarm, Lashweed Lurker, Mockery of Nature, Vexing Scuttler, and the best, Wretched Gryff.

Cards to go with emerge: Foul Emissary (expensive but useful for creating blockers), Desperate Sentry (same issues but can be big and also gives a creature when it dies), and all travelers/creatures that create value by dying (Voice of Resurgence anyone?).

Thanks! That description is actually an excerpt from a short story inspired by Elder Deep-Fiend that I wrote for fun. Maybe I'll put the rest here too. ;)

I'm not sure about Fog Bank or Sea Gate Oracle, maybe you could replace those with Chasm Skulker and Engulf the Shore or Elder Deep-Fiend

abby315 on Thoughts on Mutate?

Now that we've seen a lot of Mutate cards spoiled - including some very pushed ones like the Apex predators - and we know how the rules work, what do you all think about Mutate in Standard/60-card Magic?

I've seen a lot of comparisons to Bestow. However, now that we know that removal/bounce (but not flicker) effects destroy the whole pile of creatures, I think it's more like a fixed/better Emerge. You're pretty much sacrificing your access to the lower creatures in return for a low-cost Big Creature with Good Effect. It's slightly worse because the Mutate triggers are not cast triggers and can be Stifled by removal, but I think that's balanced by the ability to stack Mutate abilities. Also, the Mutate creature still enters the battlefield.

Therefore, similar to Emerge, I expect only the most powerful Mutate creatures to see play, similar to Elder Deep-Fiend. Does anyone think a dedicated Mutate deck will be good?

Hey ConstantVigilance. Cool deck! I've never built around the emerge mechanic before, but it looks like fun. Here are a few initial thoughts.

First, if you want to keep this as budget as possible, I'd recommend sticking to just two colors. Otherwise, all the tap lands can really slow things down. In this case, I that would probably mean dropping black - this would mean giving up Abundant Maw and Mindbender, but that doesn't seem like much of a loss. That would also allow you to run something like Sanctum of Ugin which would help you chain together multiple copies of Elder Deep-Fiend - probably the best thing you can do.

Second, I think you need some interaction early in the game to help you get to your big creatures. If you stick with black, Doom Blade is a super cheap option. If you drop black, you could run a playset of something like Unsummon - which you could also use later in the game to replay your Elder Deep-Fiend. It also wouldn't hurt to have a couple copies of Negate around for early game interaction and late game protection.

Third, for your big creatures, I would try to play a full playset of the very best options - Elder Deep-Fiend, Wretched Gryff, and maybe two copies of Conduit of Ruin. Cards like Vexing Scuttler and It of the Horrid Swarm don't seem nearly as good to me.

Last up: I can see what you're trying to do with the Stichwings, but that's such a high price to pay to get then back! I would probably drop all of them, along with the Bloodbriar, and focus on cards that give you immediate value when they enter or leave the battlefield - Blisterpod, Nest Invader, Foul Emissary, etc. (Or, if you don't care about sticking to eldrazi, you could run card draw pieces like Elvish Visionary, Feral Prowler or Floating-Dream Zubera.) In general, I would try to focus on ramp and card draw, rather than recursion. That's my thought anyway.

Best of luck!

A lot of ramp with not enough payoff. You need more big bombs to go with that 1 Pathrazer. Also, the deck needs some removal to be able to combat the opponent's threats. Brutal Expulsion, Reality Hemorrhage, and Touch of the Void could be considered. More lands that produce all 3 colors in the deck would be good also. If you want to stick to your low budget I recommend checking out some Pauper format Eldrazi lists for more ideas. Kozilek's Return and Elder Deep-Fiend also work really well together. Elder Deep-Fiend is a threat that can be cast at Instant speed on the opponents turn that will tap down some of their stuff, like their land early game for example if you can cast the Elder Deep-Fiend with its emerge cost, which you should have no issue doing.
