Brain in a Jar Discussion

Brolamog_the_Infinite_Higher on Doing nothing to draw cards. This is the life

1 week ago

Thassa, God of the Sea immediately sticks out to me as a card that doesn't synergize well, since you seem to be based more on slinging spells than making big creatures unblockable. Also not a huge fan of Brain in a Jar or Cathartic Reunion as BiaJ is rather mana intensive and Cathartic Reunion is susceptable to counterspells and can be slightly awkward to play.

Wow thanks for all the feedback tappedout!

Eredes Bleh-- Good point, I forgot that's a curse and not just an "any opponent" enchantment. I don't love the self mill with Winds of Rebuke (it never fails I end up milling my own Fraying Sanity), but it's probably a good sideboard option against PW heavy decks.

frogkill45 That's a good call. My PW plan was just countermagic, but a little removal is also good and gives us a chance to survive if we need to tap out for a turn and they drop a Gideon or something.

n4pesto I'm not a huge fan of Brain in a Jar, it's timing is kind of fragile and I'd rather just draw another bouncer. There's also no real advantage to milling out in one shot most of the time.

Airwings I won't lie-- agro is a tough matchup. The majority of my losses in play testing with friends have been to fast zombies. I usually just side in all my creature countermagic and be more willing to chump block.

MTGUniversity Thanks!

How about Brain in a Jar so you can play 2 startled awakes with sanity on board. It's no joke to mill 52 in a turn. Also you should probably add some gy hate in your sb in case of shuffle-in effects.

incesticus on HOU - Grixis Control

You control playing, Bolas worshipping, grixis loving, megadeth quoting sum'bitch. I've been lookin' at this deck for awhile, and I'm extremely excited to enter into the control field as a minion to our lord and savior, Nicol Bolas. This list has been an invaluable resource to utilize as a competitive grixis standard deck, especially with your detailed explanations and statistics. I'm hoping to include some funkier, more casual stuff, like Insult. The dream was to create a deck that comboes Shadow of the Grave with cycling and stuff like Chandra, Flamecaller, Collective Defiance, Fateful Showdown, Cathartic Reunion to draw boats of cards at once, and run graveyard and discard synergies, such as Faith of the Devoted or something like Rise from the Tides. I thought about Brain in a Jar to make discard spells instant, but the whole thing feels a little janky. Any ideas?

Thanks, and HAIL BOLAS

You need to be able to play Rise from the Tides as early as possible. In order to do this, Brain in a Jar and/or As Foretold need to be prominent in this deck. If you can play Rise from the Tides followed by Part the Waterveil, even better.

I would be tempted to replace Comparative Analysis with Compelling Argument, then drop Compelling Deterrence for at least 1 Part the Waterveil and maybe 1 or 2 Niblis of Frost in your mainboard

I have thought about As Foretold and I think it would be pretty good, but I would probably need to change the deck up if I did. Brain in a Jar let's me cast Rise from the Tides at the end of my opponent's turn so I can untap and swing in without having to worry about interaction too much. If I do use As Foretold I may replace the Rise from the Tides for Metallurgic Summonings and make it less of a one turn kill deck and more value based. It seems like it is definitely worth some testing.

Aether Vial springs to mind as a way to drop creatures and still hold up mana. Maybe some sort to flash creature like Harbinger of the Tides. If you want to play with what comes in and out of your graveyard, you could splash green for Eternal Witness. I've always liked the idea of free spells, so also consider Brain in a Jar and As Foretold. They're mana intensive but I've been testing brain in a polymorph deck and enjoying the results

Brain in a Jar might be helpful too.
