Knowledge Pool

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.

Suns_Champion on The EDH Deck Building Process ...

  • New players
  • Established players who are new to deckbuilding
  • Deckbuilders who want to take their deckbuilding to the "next level"
  • Experienced deckbuilders who might find a new trick or new perspective

This series is aimed at new-intermediate players and deck builders, but I'm hoping there's something for everyone here. And if not, experienced deck builders can still comment and critique with their own building process, adding to the Knowledge Pool!

king-saproling on Ink-Treader Splice

Glad I could help! Dovescape, Possibility Storm and Knowledge Pool would actually be more for control and value rather than chaos. When you target Ink with a spell, he will trigger and copy it for all other creatures, and one of the aforementioned 3 cards will trigger as well, so you will get the effects of the first spell for every creature minus the original iteration that targeted Ink. So you can still play mostly unhindered through Dovescape, Possibility Storm or Knowledge Pool while your opponents struggle with it. Also, Possibility Storm and Knowledge Pool effectively turn all your instants and sorceries into 2 spells for the price of one, as the copies of the first spell will still resolve and you will cast the second spell for nothing. Like splicing without having to pay a splice cost!

Thanks king-saproling!! Those suggestions are great. I intentionally avoided cards that said "target creature you control", because this deck ends up giving your opponents a lot of creatures, and when the card specifies "creature you control" you can't copy a spell that targets Ink-Treader Nephilim for creatures controlled by your opponents. That being said, I love Heat Shimmer, Snap, Depths of Desire and Debt of Loyalty. Lastly, I love a good chaos deck as much as the next guy, but Dovescape, Possibility Storm and Knowledge Pool just aren't really what this particular deck is looking to do.

Nice list! Twinflame and Heat Shimmer would be all-stars here, definitely recommend them. Since they give the token copies haste, it's easy to generate infinite mana with a mana dork and something like Eternal Witness.

You might like these too: Harabaz Druid, Cackling Counterpart, Quasiduplicate, Repudiate / Replicate, Snap, Depths of Desire, Archaeomancer, Harnessed Lightning, Debt of Loyalty, Fiery Gambit, Dovescape, Possibility Storm, Knowledge Pool

griffstick on Help with Long Game Voltron ...

I spelled it soulbound that's why it was auto corrected to southbound which is a common term when telling someone how to find you on the road specifically ones that use jug handle uturns. I believe states outside of NJ call them roundabouts. Anyway, some other combos are Lavinia, Azorius Renegade + Knowledge Pool this makes it so that your opponents can't cast spells anymore.

There is Rest in Peace + Helm of Obedience exiling library one player at a time.

You could play Nature's Revolt and Linvala, Keeper of Silence rendering there lands useless or Elesh Norn, Grand Cenobite killing them all.

jasonkrivera on Alela, Enchantress of the Fae

I'm building Alela and I was planning on running the combo of Sword of the Meek and Thopter Foundry.

At the end of the turn before your turn, any spare mana you have creates a flying Thopter (which Alela boosts) and gains you 1 life. Throw in Ashnod's Altar and you have infinite tokens and infinite life, and kill everyone else when those tokens can attack.

As game finishers, I'm running Opalescence and Enchanted Evening. And I was thinking about Karn, the Great Creator and Mycosynth Lattice, and/or Lavinia, Azorius Renegade with Knowledge Pool.

Maybe these combos are too mean though?

Knowledge Pool immediately comes to mind. Every time they cast a spell, they're forced to cast a second, different spell. Knowledge Pool combines nicely with cards like Lavinia, Azorius Renegade to lock opponents out of the game.

abbatromebone on WU Prison Control (NEED HELP FIXING!)

2 months ago
  • The hardest thing to do in UW control is to make a lock. There are Knowledge Pool locks you can do. You have a pillow fort deck not a prison deck. Prison deck lock your opponent out leaving them to slowly watch you whittle them down. Pillow fort decks have cards like ghostly prism.
  • As a UW control deck you want PRO-active plays. So counter spells. Manaleak is very good and even seen in competive play. Based on your budget i suggest you engineer your deck to what you play against. If that's creatures essence scatter is good, if its not that negate is good. Dovin's Veto is hard to cast turn 2 because of your mana base, i recommend getting some dual lands. Itll make casting spells easier.
  • Im willing to help make this deck for you, I would just like a little more information. Pillow fort or pison deck? Budget? What is the most enjoyable part of playing?
