Knowledge Pool


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.

Knowledge Pool Discussion

What are your thoughts on Knowledge Pool ? Could disrupt opponents while you beat their faces, and interacts with Ruric similarly to Possibility Storm. Also Helm of the Host might be worth it. Multiple Rurics? Yes please!

Gidgetimer on Choosing Piles with Lili

1 Welder isn't a combo piece. It is recursion.

2 You said you challenge me to find a scenario where making piles was more beneficial and I gave you one without much thought. TBH the untapped monolith is less likely than double welder.

3 My point wasn't that it was equally likely for piles to be as strong as choosing. The point was that it is possible for piles to be stronger in some scenarios. Therefore it is not as simple as "choosing is stronger".

4 If you don't like multiple copies of the same card let's do an Oloro EDH deck (again off the top of my head).

Teferi, Mage of Zhalfir

Knowledge Pool

Exquisite Blood

Vizkopa Guildmage




Hallowed Fountain

Ancient Tomb

Lili needs to deal with both a hard lock and the combo that the lock allowed them to get out. The one making the piles gets to decide if the picker gets to deal with one or both.

The point isn't that these scenarios are likely. It is that they exist and therefore the statement "choosing is always better than making piles" is false.

I am done giving scenarios in which you can make make piles so that either win or neither win. You were unaware that the situations exist and that is fine. You are now trying to act as if you had stopped at saying they are corner cases and didn't "challenge" me to prove what I said was true. They are corner cases. But they exist.

Gidgetimer on Golos & Rule of Law

"Can't" beats "can" in MTG. The restriction to only casting one spell a turn means that under no circumstances can you cast more than one.

Knowledge Pool just exiles the card, you don't cast another.

Possibility Storm just has you reveal cards and put them on the bottom.

Golos only lets you cast one and only if you haven't already

chronatog dose not seem to be that good of a win con. Have you considered Decimator Web ? also, you could run Jace, Unraveler of Secrets as your other erayo. You can also play Curse of Exhaustion as a one-sided rule of law. You can also run Knowledge Pool as another erayo. I think you can cut some thopters and memnites for a more control package, like Path to Exile , Cryptic Command . your kytheon does not seem too good here, meybe switch him for another gideon. I myself tried to build this lockout shell, but I gave up. Nice to see someone trying to do this!

Ashiok's Dream Realm

Whenever a spell is cast, if it was cast from a player's hand, exile it.

At the beginning of each player's upkeep, they may cast one spell exiled with Ashiok's Dream Realm.

I'm genuinely unsure how to destroy it. I guess Cataclysm , Apocalypse ...I mean Merciless Eviction , Austere Command , Cleansing Nova , and all spot removal require a sizable amount of coordination.

Perplexing Chimera and Knowledge Pool , but slower and able to be played earlier.

I'd like to see someone else's most annoying card!

@bushido_man96: Already made more cuts, & added them to the Maybeboard if any are good. As for Knowledge Pool , I'm running Teferi, Mage of Zhalfir ; though that might warrant a cut also. Any opinions on that & "The Maybeboard Hotseat" thus far?

Ok, here we go...

Hexdrinker is cool, but...eventually, you can't even target it. And it doesn't have trample. Possible cut. Why Knowledge Pool ? It just seems weird. I'd cut it. And Gelatinous Genesis . And I'm on the fence about Orochi Hatchery . Not sure you need it.

You should run a Rogue's Passage so you can push one of your big fatties through. Some X creatures you don't have in here: Anthroplasm , Kraklin, and Verdeloth the Ancient . Verdy would be very worth running, I think.

That's the best I can do for now.

Here are two Kruphix decks to mull over, as well:

darkone8 on What´s in your Hand?

Seems not bad. If you're trying to play a control deck, I'd recommend tuning your counter suite. Instead of playing Hostage Taker , play Oblivion Ring . The Wanderer seems like a less good idea because it's really slow for its effect. I'd recommend finding some other hard removal spells ( Mortify , Doom Blade , etc.) and trying to play more Jaces to help with card draw to access your control spells. I would also recommend looking into other dual lands and fetch lands. To top things off, you can play Rule of Law or Eidolon of Rhetoric paired with Knowledge Pool to stalemate the game. If you're looking for alternate win conditions/combos, just let me know.
