Knowledge Pool

Artifact

Imprint — When Knowledge Pool enters the battlefield, each player exiles the top three cards of his or her library.

Whenever a player casts a spell from his or her hand, that player exiles it. If the player does, he or she may cast another nonland card exiled with Knowledge Pool without paying that card's mana cost.

Oh and card advantage is weak in this deck only relying on Ugin, the Ineffable and Knowledge Pool. I do get to use the OPs win cons with Pool though, so that's something as well.

So I probably should of mentioned some of the problems with the deck lol.

  1. Ok, yes Knowledge Pool is a cast trigger, so it wouldn't trigger if the spell is already cast. This is a problem with specifically Knowledge Pool and Prototype Portal. In order do both in 1 turn would cost 10 mana and would only happen as fast as turn 4 if you have Tron active with 2 towers. So more than likely you would be getting this combo if portal was under a pool to begin with or beyond turn 4.

  2. This would still be a lock then, either cast Bronze Bombshell and take 7 or let your spell be ate by the pool.

  3. This is true, but my other modern deck right now is Izzit Coin Flip, so I'll take that chance. :P

  4. Now I forgot about Boseiju, Who Endures. And Shattering Spree may still go under the pool, but it's replicated copies would be a problem. As you said will need to find solutions for this. Spellskite would work I guess. Oh yeah and to fit the theme, Jester's Cap could hit 3 Boseiju lol (I don't this this is good). And Pithing Needle can stop Boseiju also since it's an activated ability. This is just off the top of my head.

  5. I just wanna lol

I'm trying to go through and see other things that are problems and if I would have to choose one it would be that Mystifying Maze only hits attacking creatures that the OP has, so I can't use it to temporarily get rid of Soulless Jailer so I can cast noncreature spells. The only thing that comes to head atm is Endless Sands, but I don't like that. Will be looking for something for that as well.

The only thing I can think of is Teferi's interaction with Possibility Storm locking opponents out of their hands, but mono blue decks also have that with Knowledge Pool.

I love Vorthos decks though, and would 100% be willing to play against it!

Imprint — When ~ enters the battlefield, each player exiles the top three cards of their library.

Players can’t draw cards

At the beginning of each player's draw step, that player exiles the top card of their library. If it's a land card, the player puts it onto the battlefield. Otherwise, the player casts it without paying its mana cost if able.

Whenever a player casts a spell, that player exiles it. If the player does, they may cast a spell from among other cards exiled with ~ without paying its mana cost.

Just wait until I get my Rule of Law

2/4

It’s a mashup of Knowledge Pool and Omen Machine that synergies the two together. Make another game ruining card

Madcookie on Knowledge pool, Void mirror and …

Does tax effects like Grand Arbiter Augustin IV fizzle the Knowledge Pool + Void Mirror lock by allowing the opponents to pay 1 extra mana (assuming they pick colored) to cast a spell from the pool?

I'm fairly sure it's a nonbo but want to be extra sure.

CoarselyRefined Not quite. Although Teferi, Mage of Zhalfir is worded as "Each opponent can cast spells only at any time they could cast a sorcery."" it actually means "Each opponent can only cast spells during their main phase, when the stack is empty". The way Knowledge Pool works is the opponent casts a spell, Knowledge Pool triggers and exiles it, instructing the opponent to choose and cast a spell from among the previously exiled cards. He chooses one and attempts to cast it, however the thing that allows him to do so it the Knowledge Pool's trigger itself, which is still on the stack. Teferi, Mage of Zhalfir sees this and say "No, you can only cast spells when the stack is empty" and stops the spell. That's how the lock works.

Anyway, thanks for the Lavinia, Azorius Renegade suggestion. I'll try to get my hands on one soon. Cheers!

Wuzibo Buy some Chaos Warps

I'm getting a lot of "I get locked out playing my favorite deck so I wanna lock out players too"-vibes. The one difference between Iona and all other problematic cards you named, is that Iona can be your commander, making sure you still have access to it after Oblivion Stone etc. That's where it differs from Leyline of the Void which, yes, can be in play from turn 0, but there's going to be a lot of games where it won't, and it probably won't return after the O-stone.

Iona's also a creature, making sure cards like Ephemerate will customize the color chosen to whatever you need whenever you need it, protecting it from removal in the process.

If you want to lock people out of casting spells, there's still plenty of ways to do it, but it's by combining cards together, not 1 card that does the entire thing for you. With Palinchron you need a mana doubler, with Heartless Hidetsugu you need a damage doubler and a way not to die, with Lavinia, Azorius Renegade you need Knowledge Pool, with Decree of Silence you need Solemnity.

With Iona, Shield of Emeria you need nothing. With Paradox Engine you basically need anything, it's not restrictive enough in its synergies to not be overpowered, while leading to 20 minute turns where one player gets to play all the magic while the others get to watch.

If you're scared of Mindbreak Trap, just play Rule of Law. If your deck doesn't function because of a single card in play, it's badly built. You could still go Sol Ring into Thran Dynamo for Wurmcoil Engine t3 and kill the leyline player. That also stops it from being a problem. Those are all cards that would be amazing in a Daretti deck and doesn't need to break the color pie to get you out of a sticky situation. If you can only do Junk Diver Scrap Trawler loops, that's way more of a restriction on your deck and way easier to devise a backup strategy for than "playing a monocolor".

The rationale for banning Iona is that it leads to a play experience the rules committee wants to discourage, which is locking people out of playing the game. That's paraphrased from the ban article. Not locking out from winning, which is what you're talking about. Also, discourage, not prevent. You can still do it, but a flagship commander for that strategy that, no matter how you build her, it's gonna cause that bad time, that gets banned. Braids, Cabal Minion is banned for the same reason.

Your rationale of "they can now ban cards because they lead to unfun gameplay? They should ban every card that ever blocked my fun then" sounds very entitled, and hard to agree with. It makes you sound as much of a salty bad player as you blame the RC to be.

Three cards that I really liked were Mogg Infestation, Inventors' Fair, and Indomitable Creativity

Some cards I have questions about however:

Crucible of Worlds, I only see two lands that you are sacrificing and I don't see a lot of things that put lands in your graveyard. I feel that this is kind of a do nothing card in this deck.

Knowledge Pool, I feel like in order to make this worth it you really need the other cards that lock other people out. It's ok-ish as a chaos card, but there are better cards to cause mayhem at the table.

Reliquary Tower, you don't have a way in the deck to draw a lot of cards. This is another do nothing card.

Krark's Thumb, there are only 3 cards in your deck that deal with coin flips. Is it worth it to use this card?

Altar of the Brood, even if you get this trigger twice a turn with norin and Panharmonicon it's not really doing much. It will actually hurt you if you play this against a graveyard deck that want stuff in the yard anyway.

Brand, you don't have anything other than Confusion in the Ranks that gives opponent stuff, when you use confusion to give norin, when he exiles he comes back to your battlefield anyway. Not sure this is doing much for you.

Worldfire, this card needs a solid strategy to be good. Like protecting your board with Teferi's Protection or something before you cast it. Since norin can't actually do damage since he exiles himself when he attacks, this is kind of a nonbo in this deck.

I feel like you are trying to pull this deck in a lot of different directions all at once. Kind of a jack of all trades master of none problem. I would suggest finding one or two things and work on making everything in the deck synergise with that. I also think that this deck might work better with a different commander, there aren't many cards that actually interact with norin in this deck.

Lastly, you should definitely put Genesis Chamber in this deck. It's way too good with norin not to include.
