Detention Sphere Discussion

Kjartan on USA control, needs help

4 hours ago

3 Keranos is definately overdoing it.

And if you want Nahiri, you might want an Emrakul, though she is good enough on her own.

Less creatures in general would be a good idea I think.

But 4 of them should probably be Snapcaster.

Also consider Ancestral Vision and Blessed Alliance

For the mana base, Flooded Strand is legal now and should probably replace your Arid Mesas and 1 of your other lands.

Also, Ghost Quarter should probably replace Desolate Lighthouse as your Colorless/utility land of choice.

For the sideboard.

some good includes are Stony Silence, Rest in Peace, Anger of the Gods, Negate, Dispel, Supreme Verdict, Engineered Explosives, Deflecting Palm, Detention Sphere, and Wear / Tear

Here's my UWR deck if you have any interest:

ej133 on Serpent in the ice

4 days ago

Hm, I don't know, man... but, the mix of creatures you're running seems really sloppy. I mean, what is the Isamaru, Hound of Konda good for? And the 4 copies of Cryptic Serpent and Delver of Secrets  Flip being bounced back to your hand due to the effect of Awoken Horror  Flip look a little out of place.

I love UW Control, and I play it myself as TrUWe Control. I know some cards are hella expensive, like Snapcaster Mage, Celestial Colonnade and Cryptic Command, but you have a lot of cheap options that are nearly auto-include in any azorius build:

  • Serum Visions - our one and only cantrip in modern.
  • Blessed Alliance - although this is not necessarily a 4-of, is aggro kryptonite and you need some.
  • Path to Exile - THE Removal for modern. Just had its third or fourth reprint, so it's time to get yours.
  • Detention Sphere - doesn't really seems like mainboard material, right? haha But, I've been using two and they're extremely useful.
  • Aaaand lands. You run so few lands. You'd might want to use some more, since you can't afford losing land drops.

But then you might ask yourself: "How the fuck will I win if I just take out all of my creatures?". Yes, that's though. Awoken Horror  Flip by itself is a solid wincon, but he gets Fatal Pushed very easily, so you can't relay solely on him to win. I'd recommend some planeswalker, like Gideon Jura (who is having a recent price spike) and Elspeth, Sun's Champion and even Narset Transcendent, but I don't know about your budget.

Anyhow, I hope my tips helped anything about your list.See ya!

veritas723 on Brago EDH (Looking for a Wincon)

4 days ago

some creatures you might consider. Sunblast Angel, Frost Titan, Phyrexian Ingester

utility creatures... or trix creatures Resolute Archangel, Mnemonic Wall, Knight-Captain of Eos

I also think some of the "detain" creatures are a waste. especially when there's plenty of exile creatures. Fiend Hunter Restoration Angel Angel of Serenity things like that. if you pair it with blink gimmicks, you detain something forever.

Also think a spell like Detention Sphere is meh in edh, unless you're naming like sol ring. i like Prison Term locks down a thing, and then can be moved to another thing. but that's just my personal preference... i find i have answers for misc things, what i like is being able to see what's played, and lock a new creature down.

other win-con ideas. swarm ball creatures like Myr Battlesphere

I also like Reality Acid in a deck like this.

i also think... altar of the brood is kinda meh. but maybe adding other etb mill creatures could help with that plan. also... maybe gilded lotus is too much, or tsabo's web. Even something like sphynx kinda meh. you'll get more action blinking mulldrifter or other draw/recycle cards if your engine is going. and the life... from rev is kinda meh. there's prob a few cuts for better cards. I'd kinda want more wraths. and maybe some bigger bodies. and trim out meh artifacts/enchants

What does your budget look like? I took a gander at your decks and for the price tags the concepts of the Azorius decks seem pretty sound for the most part... your Dimir deck is like half built but your "maybeboard" includes most Dimir mill staples

for control i would advise a minimum of 24 lands with either 4-8 sources for draw and or topdeck manipulation or tutoring. Serum Visions/Wall of Omens/Omenspeaker/Drift of Phantasms/Muddle the Mixture as some examples.

classic control elements like counters and removal: Mana Leak/Vapor Snag/Path to Exile/Ghostly Prison/Detention Sphere/Supreme Verdict

and once you have a GRIP on the game a win condition like Elspeth, Sun's Champion or you can do turbofog using Azor's Elocutors or Luminarch Ascension

sylvannos on Am I onto something here? ...

If you get rid of Myth Realized and Isochron Scepter, replacing them with something more reliable, you actually have the start of a strong deck on your hands. You'll have to move a few things around (like Dispel/Spell Pierce/Negate/Remand instead of Dissipate), but plain U/W puts up solid results.

The archetype benefits from having a simpler mana base. This allows you to play things like Ghost Quarter and not run into any problems.

I'd suggest moving away from Myth Realized and Isochron Scepter in favor of either a low-mana tempo strategy or a slower, control strategy with a big finisher.

For the more tempo-based deck, Thing in the Ice  Flip is a good choice. I'd also include some number of Geist of Saint Traft, however many you can afford within your budget.

For the larger, control strategy, Dragonlord Ojutai and Sphinx's Revelation will just fuck people's shit right up shit creek. If you can afford to get any of the higher mana cost planeswalkers that are good in Modern, those can work too. Elspeth, Sun's Champion and Jace, Architect of Thought stand out the most.

Wall of Omens and Restoration Angel can also put a lot of work in, especially together. Restoration Angel by herself will make any hexproof creature you control really hard to kill.

Other budget options I'd suggest (in addition to the above) are:

nslm on Am I onto something here? ...

I know it's not exactly a new idea, but I saw Myth Realized and Isochron Scepter and thought I could really build something around them. Then I remembered Thing in the Ice  Flip and thought it would be a perfect fit. And I know that there are cards like Disallow Serum Visions or Detention Sphere that could really improve the deck (not even gonna mention the mana because it's obvious), but my budget is limited. What I'm really asking for is opinions about the general idea of the deck. As it says on the title, am I onto something here?

So far this is the list I've built:

Isochron Myth

I have been playing it for some days (MTGO, Just for fun room) and actually winning most of the time. Maybe it's the meta, maybe the deck would crumble against tougher opposition. But so far it's been solid and a lot of fun.Any feedback would be most welcome. Has it been a lucky patch or have I built something actually good?

Detention Sphere has 2 triggered abilities, one when it enters, and one when it leaves.

800.4d If an object that would be owned by a player who has left the game would be created in any zone, it isnt created. If a triggered ability that would be controlled by a player who has left the game would be put onto the stack, it isnt put on the stack.

If the player controlling the D-sphere dies or leaves the game, it's LTB ability never resolves, so the exiled cards never return.

First, you can link cards with double brackets. Detention Sphere

This will help people sort out your question.

As for the answer,

800.4a When a player leaves the game, all objects (see rule 109) owned by that player leave the game and any effects which give that player control of any objects or players end. Then, if that player controlled any objects on the stack not represented by cards, those objects cease to exist. Then, if there are any objects still controlled by that player, those objects are exiled. This is not a state-based action. It happens as soon as the player leaves the game. If the player who left the game had priority at the time he or she left, priority passes to the next player in turn order who’s still in the game.
This is the rule regarding players leaving the game. Everything they own ceases to exist. As far as I know, this does not trigger Detention Sphere's second triggered ability, which returns the permanents to the battlefield. Even if it does, that trigger would then also cease to exist before it can resolve. In short, the cards Detention Sphere exiled will remain in exile.

800.4d If an object that would be owned by a player who has left the game would be created in any zone, it isn’t created. If a triggered ability that would be controlled by a player who has left the game would be put onto the stack, it isn’t put on the stack.

This further expands, once the player has left the game, any triggered ability that would be put onto the stack under their control is not, so Detention Sphere's trigger would never even hit the stack.
