TheAnnihilator on bant control

I'm not actually certain that you need green here. Fog is sortof a weak card, since it doesn't actually answer any threats, it only buys you a turn. Regardless, if it's an effect you want to have, white already has Ethereal Haze.

I also think Kitchen Finks and Thragtusk should be on your radar. A near way to go green would also be Glittering Wish to get a Verdict, Detention Sphere, Sigarda, Host of Herons, Fracturing Gust etc. from the board.

Well here we go. I have almost all the cards. The only ones missing are 1 Detention Sphere, 1 Supreme Verdict, and the 3 Wall of Omens(which will be changed eventually).

Today i'm going to be playing in a modern tournament to see how it goes without them. Until i get these cards i've put in 1 Peek and 4 Spreading Seas. I think Spreading Seas might be a good replacement for Wall of Omens as my lgs plays Tron a lot and this would be decent for tryig to stop it.

After the tournament tonight i'll post an update lettig you know how it went. Wish me luck lol

Gates88 on [List - Multiplayer] EDH Generals by Tier

sonnet666 I appreciate your response. I'll start off by saying that mentioning the obvious tier 1s (Thrasios, Zur, Tazri) was really just for completeness' sake. In hindsight, it was just a waste of time to mention them and I regret bringing it up.

You're also completely right about Mairsil, I just straight-up didn't do any research on the way that deck was going at all. The Mirror-Mad Phantasm line is great in a Doomsday shell and it's the main draw for it. The Razaketh line is a little bit more questionable since it requires creatures in play and Grixis has few creatures it actually wants to run and it can only be uses once a turn, but turning your commander into Diabolic Intent isn't bad by any means. I still think that Kess and Jeleva are clearly superior Grixis commanders though since they can have 99 cards that are gas and not dilute their deck at all. It's similar to Teferi vs Arcum Dagsson. Teferi runs a couple of bad cards or cards that aren't good for reasons other than The Chain Veil combo (Thran Dynamo, Gilded Lotus, and The Chain Veil itself would be useless without the rules interaction that allows for the combo), but Arcum runs a lot more bad cards because it needs to have artifact creatures to sacrifice and most artifact creatures suck. There's less of a difference between Kess/Jeleva and Mairsil than there is between Teferi and Arcum Dagsson in terms of number of different cards in each deck, but the principle is that Mairsil requires more build-around cards than the other Grixis generals and it hurts him overall. Regardless, I apologize for my ignorance and I think that tier 2 can be a valid placement for now.

I forgot that Razaketh was your pet deck. I won't bother arguing with you about it then.

I disagree about Karador. It's true that he reduces his own cost, but only if creatures are in the graveyard, which there will probably be few unless someone has wiped or you have Survival of the Fittest/Fauna Shaman. In the latter case, you probably won't need Karador since you'll be able to tutor up Boonweaver Giant and a sac outlet (or whatever you're comboing with) relatively quickly anyway. It's true that he casts creatures from your graveyard, but only one per turn, so saying he effectively makes your graveyard your hand is a huge overexaggeration. Being able to cast creatures from the yard is also only useful if you have creatures in the yard, which is not too difficult to achieve but not always a common gamestate. Compare this to Tymna, who generates value at every stage of the game as long as you have creatures, and he looks much less favorable. The Abzan Boonweaver strategy has never really relied on the commander for anything but value, so the fact that Tymna can create more value more quickly than Karador speaks to her advantages and his weaknesses. If you won't put him in tier 3, consider at least moving him down to tier 2.5.

Everything I said about Teferi was in jest. In fact, I believe I even said later in my post that I was just joking around when I talked trash about Teferi. I don't post a lot on tappedout anymore so I don't blame people for not knowing, but I am a Teferi main and although I don't consider myself an expert, I know the deck pretty well. The Blood Pod matchup is probably Teferi's worst matchup (it's even worse than Ruric Thar, which is saying a lot), but it's not enough to keep him out of the top tiers.

Your suggestions for additions to Teferi are understandable but misguided. The primary reason that Paradox Engine and Dramatic Scepter aren't in Teferi is partially because the deck already has two and a half alternate win conditions - Rings of Brighthearth+Basalt Monolith is one, Power Artifact+Monolith is two, and Teferi+Stasis is almost a win condition - and doesn't need to dilute itself by running any more. All the cards I just mentioned are also good on their own - Monoliths for obvious reasons, Rings of Brighthearth for its ability to copy Teferi or Tezzeret's abilities, and Power Artifact for generating more mana while comboing with The Chain Veil. Neither Dramatic Reversal nor Isochron Scepter have utility on their own. Imprinting a Counterspell or a bounce spell on Isochron Scepter is a fine strategy in 1v1 (and I used to play Scepter Chant back in Mirrodin-era Extended, so I know how it feels), but it ultimately isn't good enough in the midgame to be worth running. Dramatic Reversal is effectively just a ritual and has very little utility outside of the combo. We already have access to a lot of good rituals, like Teferi for example, and we don't need another one that badly. Paradox Engine is too reliant on cards that are already in hand and costs 5 mana. Why would you tutor for a situationally relevant card that costs more to cast than The Chain Veil and is not a guaranteed combo? Furthermore, running these additional win conditions would require multiple cuts to either the manabase, card draw spells, counterspells, or bounce spells, which would weaken the deck in some other aspect. It's just not worth it to run these cards.

And just because Manifold Insights isn't as good as Lim-Dul's Vault doesn't mean it's trash. Being able to see 10 cards deep and getting 3 nonlands is a big deal, even if it's the three worst cards in that set. The fail state of Manifold Insights is either getting your 3 worst mana rocks or your 2 worst mana rocks and a counterspell that's not relevant (ex. Flusterstorm at a table full of creature-heavy decks). That's not great, but it's still 3 cards that will likely not be dead. The only major drawback to the card is its sorcery speed, which is unfortunate but ultimately not a dealbreaker. And obviously the card is unplayable with fewer than 3 opponents, but ideally that shouldn't happen.

Finally, do not under any circumstance go with a different decklist than what you have posted. Even though it does not match my personal list and I don't agree with every card choice in it (cough Expedition Map cough), the comprehensiveness of the primer section is encyclopedic, which makes it an excellent resource. It talks about primary combo lines, alternate lines, matchups, single card choices, and even budget alternatives. If you are already vaguely familiar with competitive EDH, you could become a somewhat competent Teferi player just by reading that primer and goldfishing a bit. Something drastic would need to happen in order for that primer to become irrelevant, on the scale of a major banning or maybe a change to the rules interaction between Teferi and The Chain Veil.

As far as Yidris goes, Jim has talked a lot on the discord about his deck and the gist of it is that Yidris is plan B. Plan A is jamming a turn 3 Ad Nauseam, which he aims to do as often as possible. That should give you an idea of how important Yidris actually is to the deck. His current list also still runs Mass Hysteria, so Concordant Crossroads could be a possible addition to improve it. I doubt Need for Speed would work well though, it overlaps with Rain of Filth too much and you'd rather sac your lands for mana than give your dorks haste in most circumstances.

I would argue that The Gitrog Monster can fight through counterspells more easily than Sidisi, Undead Vizier can because of cards like City of Solitude and Autumn's Veil, but you're right in that both decks are linear and somewhat fragile. Gitrog makes up for this by being able to clean up at really weird times, like their own cleanup step.

I think Tier 3 is solid for Atraxa. She has pubstomp written all over her, so it makes sense to put her in the pubstomp tier.

When I said that Dimir was a limited color identity, I meant in terms of what it can answer and how well it can answer it, specifically in regards to artifacts and enchantments. Black can't really interact with artifacts or enchantments at all, and blue only has bounce spells or counterspells. Hurkyl's Recall and other bounce spells are only temporary, and unless you can win the turn after a bounce through countermagic for sure, you will still be in danger of the problem card resolving the following turn again. Swan Song and other counterspells are reactive, which a combo deck really doesn't want to be. Compare this to Grixis, which has access to Vandalblast and By Force, or Esper, which has access to Disenchant and Detention Sphere (in Zur), or Sultai, which has access to every good card in the format, and Dimir looks worse by comparison.Even the creature removal isn't as diverse when it comes to wipes. Dimir only has Toxic Deluge while Esper has Supreme Verdict and Grixis has Rolling Earthquake and Fire Covenant. That's really the only weakness of the color identity, but it's not a trivial weakness and it does make Dimir combo worse than Esper/Grixis/Sultai/4 color combo.

As for your question on Baral, whether High Tide isn't strong or Baral is just bad, the answer is kind of both. Baral is a commander who gets outclassed by Jace in almost every way, and although he isn't weak by any means, Jace isn't outrageously strong to begin with.Jace can loot more consistently, can get more value in the midgame when cards have been binned, and can enable double Tide turns. Baral's cost reduction is nice, but that's about the only advantage he has over Jace. Blood Pod is also pretty brutal against Baral since all the win conditions either require Islands (making it weak to Choke) or artifacts (making it weak to Null Rod and Stony Silence).

okay! Just making sure you knew that, maybe give yourself better on board control as well as maybe more diverse card layout, because something like a Detention Sphere can render your deck useless very easily

I have run mono-white prison before honestly there is a big upside to that with Heliod, God of the Sun, the reason to play blue though is Supreme Verdict, Detention Sphere, and most importantly the ability to play Negate in the side, having a counter helps you land your prison pieces which is key.

As far as cuts go I think you can turn the transmute cards into something else, especially if you are adding additional unconditional tutors. Anything that can't cycle has to be very special to be included, although I'm also not exactly sure how many cycling cards you need for the cycling combo thing to work in general. It's possible that card draw spells are mostly unnecessary with all the cycling and tutoring already going on...although you do need 7 in hand for New Perspectives to work...hard to say without testing the deck personally. I do like Treasure Cruise though since it will basically always only cost .

Some more random ideas... maybe turn Akroma's Vengeance into Wrath of God or Supreme Verdict so it doesn't kill your New Perspectives and Fluctuator. Grasp of Fate and Detention Sphere are both upgrades on Oblivion Ring too. Possessed Skaab and Restoration Gearsmith could be a great blink targets to recur cards with Astral Slide too. And Gilded Lotus and Thran Dynamo are pretty much the best ramp spells you can get in Esper, can't have too much mana. Good luck friend :)

If that is the theme you're going for I feel like there is still a lot of good options you're missing out on. Detention Sphere is great for tokens, False Prophet, Silence the Believers, Summary Dismissal, Final Judgment, Identity Crisis, Merciless Eviction, Path to Exile, Swords to Plowshares, Reality Shift, and Grasp of Fate.

redace10 on Ever Vigilant

Ah I see, that's legit, your deck is very controlling. I have a smattering of other suggestions for your theme then.

Grasp of Fate is a superb spot removal enchantment card, it's also politically charged- a lot of games opponents won't touch it cause it will hurt them to give their other opponents their stuff back too. Detention Sphere is a decent second choice if grasp of fate isn't available.

Here's two blue removal spells I'm a big fan of - Curse of the Swine and Reality Shift. Curse exiles as many creatures on the board as you need, giving back a chump token you could care less about. Very controlling. Reality Shift is an underrated card - a hard exile for just 2, and manifest is a funny mechanic to throw at an edh player. If you run into a creature heavy deck it's a gamble, otherwise Reality Shift could end up being a 2-for-1, denying them a land, spell, or non-creature permanent. It's won me the game more than once I can tell you.

Hour of Revelation is far superior to Planar Cleansing.

You run a lot of instants and sorceries, and few creatures. Narset Transcendent seems like she would be a slam dunk for this deck. Rebound would be a powerful ability to throw an quite a few of your spells, and you should see card draw more often than not from her +1.

I find my DL OJ deck changes fairly frequently. I tweak a few cards once a week or so, synergy is a tricky thing to try and build in an Ojutai deck, as I'm sure you know. Keeps the deck interesting though right? Haha.
