Detention Sphere Discussion

eeriekiller on Tier 1 Stax General?

1 day ago

I made a $60 version of Brago, King Eternal that did really well for a casual deck. Sadly, I don't have a list because it's been upgraded but here are the main pieces.

Strionic Resonator, Altar of the Brood, Sol Ring (any amount of mana rocks that produce a total of two mana), and brago = infinite mill

Strionic Resonator + Oblivion Ring/Detention Sphere + brago exiles the board permanently

Muddle the Mixture toots for Strionic Resonator

other cool cards are Peregrine Drake, Grand Arbiter Augustin IV, Thorn of Amethyst, Vryn Wingmare, Tangle Wire, Parallax Tide, Parallax Wave, Reality Acid, Stunt Double/Clever Impersonator, Traveler's Cloak, Act of Authority, Storm Crow for power, Treachery, Phyrexian Ingester, Resolute Archangel, Duplicant, Sun Titan, Genesis Chamber, Stasis (personal favorite), Mystic Remora, Lavinia of the Tenth, Lyev Skyknight, Cloudblazer, and Unquestioned Authority.

Brago plays best in a pod. 1v1, he doesn't really have a lot of time to set up his stax/combo. I hope you like the deck as much as I do!

Here is my current build.

I really don't want to run Cryptic Command purely because hitting that triple blue on turn 4 will wreck my life total, if it happens at all. I'm also not really trying to play the straight control plan where Cryptic would shine. My Mana Leak + Remand suite works well enough as a counterspell package since they are easy to cast, Remand cycles itself(and can possibly set up a good Spell Queller), and Mana Leak counters the things that I would prefer they not be allowed to cast again.

On your second point, I'm currently testing Steppe Lynx because I do a lot of fetching and I thought it might be a decent add. Like you suggested, I may cut it. But I haven't actually gotten to test it yet. If I do cut it, I may go for another spell like Boros Charm, but I wouldn't add a Path to Exile Because I already run a playset lmao.


Like I said above, I'm just testing Steppe Lynx for now, it could get cut. But it may not be as ugly duckling as you think, it was a popular pick in old Jeskai Delver decks actually! Either way, it may stay or it might not. Check back in two weeks or so to find out ;)

I like the Wandering Fumarole suggestion, I'm not sure that I would want to cut Bedlam Reveler for it though. I added that card to try and make sure I have enough gas to finish off my opponent in the endgame. That card is still in testing as well, I have not had a chance to play my deck since I added the last set of changes because I spent my weekend at prereleases instead.

On your last points, I actually run Detention Sphere as a 2-of in the sideboard, not sure if you missed that or what, but yeah it has worked out pretty well! I considered adding Supreme Verdict to the sideboard(I refuse to run sweepers in the main of this deck since it interferes with my plan so much) in my last change set but decided against it. I added a 1-of Pyroclasm in the side instead because I've found that when I need a sweeper I need it earlier than turn 4. My spot removal and counter suite takes care of the bigger stuff that Supreme Verdict would take care of normally, so I decided against it. Supreme Verdict also kills my Spell Quellers, which is very bad for my game plan overall, especially if I took care of a potentially game-changing spell with the Spell Queller, like a Blood Moon or something.

Thanks to both of you for checking out my deck and leaving comments! I really appreciate the feedback and discussion :)

Get that Lynx out of here! Lol. It's so ugly duckling here. I love the name! +1 on that.

As far as suggestions, I would find a way to include Wandering Fumarole. That card may seal games and be very cunning. Perhaps removing the 1x of Bedlam Reveler could be best.

Detention Sphere may also work wonders. Supreme Verdict is great, as a 1x of as well (especially with so much draw)

JararoNatsu on No Fun Allowed

The one major issue I see with this deck is that there is no win condition, although you have already acknowledged that. If you don't want creature cards, something like Luminarch Ascension would work. If you're shutting down an opponent each turn (which you should be), then you can attack with smaller creatures each turn and be fine. If that's the case, creatures like Meddling Mage/Reflector Mage and Spell Queller are fun, especially if you play cards like Telepathy early on.

Another thing: Instead of having enchantments that pacify creatures and board wipes, ensure that as few creatures make it to the board in the first place, and exile/Unsummon away the ones who do. The whole point of the deck is to not let the opponent do anything, rather than respond to what they have already done.

I would advise against CMC 3 counterspells. You will want as many CMC 1 or 2 counterspells as you can, so you can counter as often as you can. Remand, Dispel, Spell Pierce, and Spell Snare are good for this very reason. Mana Leak is the basic bitch of counters, if you like that one as well. I really like Rune Snag because it scales with use.

People usually suggest Snapcaster Mage, but it's incredibly expensive. Consider it if you will.

Silence and exile like Detention Sphere would work well here, especially the former. Also, Path to Exile is a better option over Swords to Plowshares. Giving the opponent an extra land to cast with (which you would just counter the spell anyway) is much better of a trade than extra health.

10 Ways to lose a Friend does what you're trying to do very well, although it hasn't been updated in two years. Aside from the atrocious amount of money spent on it (mostly on lands), it can give you some good ideas.

SlimJim83 on [Budget] UW-control

4 days ago

I leaned a couple lessons from my foray into UW control. First, as nice as Dissolve looks, it's a sideboard at best. You would be better if replacing it with Spell Snare, which hits almost everything good in Modern. Second, get some copies of Path to Exile on top of the Condemns. You can usually only surprise them once with Condemn, after that they get really cagey. Path didn't depend the situation and can get rid of static effects long before you can play Detention Sphere. Third, get Supreme Verdict. A lot of decks in Modern are midrange and sweepers generally make you tap out, so they just Mana Leak you if you try to Wrath and you're facing a really bad board state and down a card to boot. Verdict is much better because it can't be countered.

Speaking of finishers, AEtherling is crazy. He's the best budget bomb in any blue based control deck. Great choice. I usually sideboard one and mainboard the other. Look at Elspeth, Knight-Errant, Gideon Jura, and Gideon, Ally of Zendikar. I recommend them over your current planeswalker because they come down much earlier. Jace is money, though. Keep him.

Manlands like Mutavault, Blinkmoth Nexus, or Faerie Conclave are great alternate win cons. They shorten games where AEtherling is on the bottom of the deck. The Conclave also taps for .

Here are some more good cards to play in this shell. Logic Knot, a delver tax Counterspell, Ojutai's Command, the best budget modal spell in the game (gets you back a Wall, too), and Blessed Alliance, another really great modal spell.

Lastly, the one thing that will kick this deck into overdrive is a set of fetch lands. It filters your lands out and thus improving your chances of hitting answers rather than lands. I keep getting land flooded when I play mine and these will definitely fix that. Speaking of filtering, Serum Visions is awesome.

I know I've said a lot and it seems like I'm coming down hard. I'm sorry is that's the impression, I love this deck. UW Control is exciting. It's the first deck I ever played so it had a special place in my heart. This archetype is really in a great spot right now. I think it can do well at a budget level. You have a lot of the right pieces so upgrading shouldn't be a problem. The mix seems right, too. Love the deck, may you always topdeck what you need.

xyr0s on U/W Frustrating Control

4 days ago

Funny idea, but a couple of cards seem a bit too weak for modern. Like Master of Diversion - a 2/2 for 3, that has to attack to tap an opponents creature. I wouldn't play a sorcery at 2W that read "during your next turn, tap target creature your opponent controls", and this creature comes too close to that. But maybe Lyev Skyknight could do something similar? The same goes for Azorius Guildmage - it's just too expensive for what it does (although countering activated abilities can be pretty sweet) - maybe exchange it for Squelch? That way, it's a surprise when something is countered, rather than something it's possible to play around.

Grand Abolisher is in my opinion a sideboard card. It is highly relevant in some games, and in many others its a 2/2 creature. You could play Detention Sphere instead. Not that it does anything similar, it's just good removal.

Baral, Chief of Compliance feels redundant. You already have cost reduction from Grand Arbiter Augustin IV, and your instants and sorceries have little colorless cost anyway.

JararoNatsu on U/W Control

I get your interest in not overspending. It's something that every MTG player has to fight themselves over (myself included). Path to Exile doesn't give the opponent health but does give them a land. However, giving the opponent a land is worth removing a creature from the game completely for one mana.

The other two peeps above gave really good suggestions. Path to Exile, Remand, and Serum Visions are kind of your go-to in U/W Control, and then from there you grab what you want. Detention Sphere is really sexy for heavy removal, and Oblivion Ring is good as well.

Darth_Savage mentioned using Wall of Omens and I agree. It's a must-have for early games.

Like Memphismaymagic5 said (although I shall paraphrase), Mana Leak is the basic bitch of counterspells. Cheap, easy, and fun, but there are so many different counterspells that which one you use is dependent on person preference and what you're up against. I am personally a fan of having a set of Rune Snag.

One thing, though, is that you should boost your landbase to 21-22 lands. Any less and you'll risk mana drought, and you don't want more than that unless you are consistently trying to drop CMC 5+ stuff.

The great thing about U/W Control is that once you've got the basic stuff down, there are several ways in which you can take it. I recommend taking a look at other decks, seeing what people are doing, and figure out what it is that you want to do with your deck. Then go from there.

Darth_Savage on U/W Control

Echoing a bit, what JararoNatsu said, consistency is king in magic and a focussed deck with a clear win condition and plan will do better than one without. I'm assuming your on a budget, but here are some suggestions:

  1. 4x Detention Sphere, great against tokens and removes other big threats.

  2. 4x Spreading Seas, great for shutting down the hungry mana base of Modern.

  3. 4x Wall of Omens, it blocks and it draws you a card.

  4. 4x Condemn or Vapor Snag if you don't want or can't have the premium removal, these will help.

  5. 4x Void Snare bounce anything.

  6. 4x Mana Leak or Mana Tithe, playing control you need a counterspell or 2.

All these suggestions cost 3 or less mana, why? Modern is a turn 4/5 clock you need to have board control in place on turn 3 or have a sweeper like Supreme Verdict. Also Instant is better than sorcery as a general rule...
