As Conspiracy enters the battlefield, choose a creature type.

Creature cards you own that aren't in play, creature spells you control, and creatures you control are the chosen type.

Why should you waste your own creatures? Conspiracy comes to the rescue.

I actually usually don't have problems with getting mana, the majority of my problems comes from having a lack of black mana. Having more ways to get either Arcane Adaptation or Conspiracy is always really helpful. I was considering running a dragon in this deck, just so that I could come out of nowhere and have something big, even without Arcane Adaptation or Conspiracy . I will definitely add Crux of Fate and Privileged Position although I don't know about Sterling Grove . As for Farseek and Nature's Lore they definitely seem a lot better than the signets. Thanks for the help!

Well, this is an ambitious game plan but let's see if anything below is something you think might help:

Zur the Enchanter could fetch the Arcane Adaptation and put it directly into play. It looks like the deck really relies on this or Conspiracy being on the board to function optimally so with that little redundancy of effect, more search is good.

Because those 2 enchantments are so important, I would add some ways to protect them from being removed from play: Privileged Position , Sterling Grove , Spellskite , Negate [or other counterspells of choice], heck, even a Standard Bearer would suck up things like Beast Within or Chaos Warp that targeted what was making every creature a dragon. The deck looks like it can limp by without them but why go through that?

If your creatures are all going to be dragons, your boardwipe of choice is probably Crux of Fate .

I play a couple of decks in this style and Fauna Shaman is a tool I rely on to pull together creature combos.

As for the mana base, well, 5 color is tough without true duals but green does give you Farseek and Nature's Lore which might be better plays than the signets as you could tailor what color combo you needed. Cavern of Souls is of course an upgrade but also expensive so probably out of reach. YMMV but I don't know how you are able to play with only 31 lands.

NoOneOfConsequence on Commanders by Power Level [EDH Tier List]

This is probably a little embarrassing, but how does Tazri's tutor do anything useful, actually? Do you first play Conspiracy and then get Misthollow Griffin , or is there some other creature that combos with Food Chain (apart from the new squee) that's also an ally? I get that you can sink the infinite mana into her to make her and any other allies infinitely big, but iunno.

That's no argument against the competitiveness of the deck, by the way--I'm just curious.

Reaper King with Arcane Adaptation and Conspiracy is pretty brutal if you wanna go down that path. Those 2 enchantments can go into the Atogatog build too if you want something more janky.
Other than that I agree with DAWT_PLAWT with going 3 colors or even going with the new Teysa Karlov . Just make sure you go at minimum black/white/x since those are the best aristocrat colors.

Cryptolith Rite is a good mana fixer/ramp card, but you might need more ramp to go to. I'd also recommend running Zendikar Resurgent along with Mirrari's Wake. Aura Shards is a good card, too.

I'd cut Abrade and Vampiric Tutor . Abrade isn't that great, and there are better options you are already running. I think you could cut Vampiric Tutor as well. Yeah, its nice to tutor, but is there one thing you absolutely have to go get to make the deck work? I like tutors, but I don't know if its what you are looking to do here. You can cut both Arcane Adaptation and Conspiracy . You've only got a few creatures that aren't spirits already, and using two slots to make them not spirits isn't really worth it, and you've got Karmic Guide which could get them back into play if they die because they aren't buffed by your lords. You've got a decent amount of beef in your deck, so you might look at Door of Destinies and Coat of Arms . Are they just win-more cards? If you find you don't have trouble dealing damage and knocking out opponents, then you could probably scrap them, too, to make space. But play it out, and see for yourself. I know those are fun cards to cram into tribal decks, but they don't really need to go into every tribal deck. Sensei's Divining Top could probably go, too? I get that its a great EDH card, but you could probably live without it if you're needing to make room.

What I do see is a lack of card draw. You've got Rhystic Study and Beast Whisperer , which is good, but not much else. Cards like Shamanic Revelation and Rishkar's Expertise are good draw spells, and Rishkar's Expertise will let you likely drop a fatty you've just drawn. Black has great card draw options, like Greed and Phyrexian Arena to name a few. Kami of the Crescent Moon is good card draw and a spirit, which fits your theme nicely. There's also the aforementioned Zendikar Resurgent , which provides both card draw and mana ramp.

I hope I was able to help with a few cuts, at least.

SynergyBuild on Persistent Petitioners Mill Deck

1 month ago

Well, With Oona, the first option, you shouldn't run Glimpse the Unthinkable , it is mill, but it like a Lava Spike in terms of efficiency and not even the most aggro red would run Lava Spike .

Conspiracy / Arcane Adaptation / Xenograft with Oona's ability and a lot of mana some infinite combos with it, etc. actually seems pretty good. A big mana dump/Petitioners would be how I would make that deck. Almost no other mill cards, tutors for the type-changers seems efficient. Otherwise going for a lot of ramp in the form of mana rocks, card draw, and control effects and you will always have a mana dump if you hold up mana.

The High Alert Doran style list with beat down seems just bad, trying to go mill and aggro is a weak strategy, stretching yourself very thin. Grand Abolisher could still be a good commander for petitioners, however is just another mill/control strategy.

These lists can run many instant wins/free wins, like a rat colony deck, Coat of Arms , Door of Destinies , Thrumming Stone , Secret Salvage (you can Mill yourself to get one in the yard), etc. and with Oona some Isochron Scepter / Dramatic Reversal , which you work in GAAIV too by infinitely untapping the petitioners.
