Logic Knot Discussion

Brandamn on Mono Blue Tempo: “Snapdelver Hulk”

2 days ago

Honestly I would drop most the counters in place of others and more lands as you dont want to miss any land drops, I would run atleast 23 lands dropping Mutavault altogether. 4x Opt,1 more Cryptic Command, 4x Mana Leak, 3x Censor, 2x Cyclonic Rift, 2x Logic Knot and keep Remand

Would Countervailing Winds be worth playing over Logic Knot? That way, you don't have to clear out your own graveyard. Plus, it cycles itself if needed.

Definitely a good start! I like what you have going on so far. That being said, there are a few things I would change.

First off, you have way too many creatures. Reflector Mage is good but it doesn't have much of a place in Control, same with Sun Titan. I would cut all those. In their place, you need some solid counterspells.

Negate is way too specific to be run as more than a 1 of in the mainboard, so I'd cut three of those. If you're playing Casual I think you can just run 4 Counterspell. In Modern, I'd look at Cryptic Command, Rune Snag, Logic Knot, and Mana Leak.

I'd also suggest running 4 Spreading Seas and consider Opt. You don't need Honor of the Pure. I'd replace it with a third copy of Supreme Verdict.

Prairie Stream is ok but there are better lands in Blue and White. I'd look into Seachrome Coast, Flooded Strand, Hallowed Fountain, and Glacial Fortress. You also need to be running 24-25 lands in Control so you can cast multiple spells quickly. If you can afford it, definitely run 4 Celestial Colonnade. Those are way better creatures for Control than Reflector Mage or Sun Titan because they can be tapped for your counterspells and removal and are generally less vulnerable.

You also might want to consider an additional win condition or two, like AEtherling, Gideon Jura, Elspeth, Sun's Champion, Gideon, Ally of Zendikar, or Geist of Saint Traft. Dragonlord Ojutai can be pretty rad too but you have to run him with a couple copies of Minamo, School at Water's Edge or else he's too vulnerable.

I'm not sure you need 3 Detention Sphere but if it's working for you that's fine. I would strongly consider Search for Azcanta  Flip. It's easily the best cantrip in Modern Control right now.

ArchonBlue on Blue and White Lockdown

After some playtesting I decided you're right @rothgar13, Delver is too fragile for this deck. I replaced it with 4 Spreading Seas mainboard and also added a Gideon, Ally of Zendikar as an additional wincon, and switched out the two Render Silent for two Cryptic Command.

I'd also like to switch out one Logic Knot because it doesn't run well with Search for Azcanta  Flip. I was thinking of either putting one Negate mainboard or a Disallow. What do you guys think? And if I were to run additional planeswalkers, what should I run? I've been considering both Gideon Jura and Gideon of the Trials.

MVP12, Thanks for all the feedback! In terms of your suggestions, I had cryptic command before, but it was too expensive at the time. I'll add it back in. Thanks!

I was really reluctant adding Runechanter's Pike back in, but the deck needed another win condition. People countering my polymorphs really shut down the deck.

Another problem that I keep having is answering creatures while they're on the board. idk. I really like Search for azcanta in this list, and I kinda regret selling my one copy that I opened at prerelease. Two Questions: Why only one copy each of Logic Knot and Spell Snare? Also, where would I find room for 3-5 more lands?

I would definitely recommend picking up some Remand copies, it's stronger than it looks like from my experience. Although I only played Mono-U Tron. Also, Spell Burst is a better alternative to Logic Knot in this deck because you only have 7 lands that tap for U, so getting UU is difficult. Plus it has that sweet buyback so you can lock out your opponent when you get enough mana.

This is "kinda sorta" budget, but not even "kinda sorta" control.

Control (sometimes called permission) decks, play the long game, and win by using a FEW copies of cards that once resolved will inevitably win the game, see White Sun's Zenith for example.
To achieve this they tend to run a LOT of card draw/filtering (like Opt, Serum Visions, Search for Azcanta  Flip, Think Twice, Sphinx's Revelation... etc.) in general ten or more.They also run permission spells, counterspells and removal that work no questions asked. Logic Knot, Cryptic Command, Dispel - all counter spells at all stages of the game, no questions asked, on the other hand Remand & Mana Leak are the finest tempo spells the format can offer, as they are perfect at DELAYING stuff.
Same applies to targeted discard, it won't do much if tron topdecks Karn Liberated.

This deck is a very fine tempo deck, but please do't call it control. This attitude of calling everything control that has a counterspell in it fuels a multitude of misconceptions, like the format being 30% control, or that big mana decks, like tron, or valakut beat control (while in reality they beat tempo, that is for some weird reason is labelled as control)

Kaleo42 you're right that Thought Scour helps Snapcaster Mage, Search for Azcanta  Flip, and Logic Knot but (no offense) you completely didn't realize that Snapcaster Mage and Logic Knot work directly AGAINST Search for Azcanta  Flip. the mage and knot takes cards OUT of the graveyard, while azcanta needs them to stay there. the better suggestion would have been to take the azcanta out entirely, as it doesn't really do much for the deck.

also, the deck needs more creatures and 25 lands is too many.
