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.

Thanks APPLE01DOJ for having a look over. Your GB decks have been an incredible Knowledge Pool on how the deck should operate and what does/doesnt work. I only have 2 copies of Abrupt Decay. Ive been meaning to get the last 2 but havent gotten around to it. Ive been away from the real live paper magic for a month or so and wanted something familiar to play that had some chance competitively. I like Bile Blight and will test it out in my local meta.

Reflector Mage and Overwhelming Splendor are good options, but for the truly daring, I recommend Mind's Dilation, Shared Fate, and Knowledge Pool. For something even more audacious, give Timesifter a try.

Oh yeah! I forgot to put that back in when I was playing with the land base. Thanks!

Actually the neat thing about Knowledge Pool is alternative costs cant be paid for spells cast from it so Im fairly safe from Vandalblast as long as Padeem is out. Aura Shards its the same deal. Just get Padeem out first before putting down anything important.

Sadly I had to cross Treasure Mage off the guest list a long while back. He kept broadcasting big plays to the table, so Kuldotha Forgemaster took his invite instead.

That Metalwork Colossus is pretty sweet but too easy to block, so maybe...

Thanks EventuallyClassy ! I was running Ethereal Usher for a long time but I replaced it with Transmute Artifact. So far it's been a pretty good change - with Thran Dynamo on the field I can tap it and the sacrifice it to Transmute Artifact's effect and I end up with a Knowledge Pool on the board for 5 mana where as Ethereal Usher I have to dish out 9 mana to get the same effect. I'm also trying to add in a few more win conditions that win outright (rather then slogging through a Knowledge Pool lockdown).

I was a bit leery about running that many extra turn cards but they are never dead cards - that is they replace themselves at worst. Time Stretch is just to expensive/late game but so far the other extra turn cards have worked out well.

Yeah, I know what you mean. In the back of my mind, I'm thinking "what if it my opponent got it?"

But it just means that we have to be careful when landing Knowledge Pool. I've been using Elixir of Immortality as mill protection, since you can bounce it with the ability on the stack for future uses and when the opponent uses it, it just adds an extra card in your deck to cast into the pool. I've been thinking about Pulse of the Grid for the same reason. If an opponent used it, it would (usually) give me another instant to throw back into the pool.

Haha, that's great. Will definitely find a spot for Mirage Mirror.I haven't got it out yet, but in theory the only real target for Mirrorworks is Knowledge Pool and Phyrexian Metamorph to clone Knowledge Pool, but then again Knowledge Pool is my win condition. Otherwise I can understand changing it for more card draw. I could see taking out Time Reversal for Mind's Eye tho. Since it's mostly a protection against mill, but I have to be careful because it could easily end up on the opponents side with this deck until 2-3 Knowledge Pool are on my side of the board.

Hey cool! We have very similar decks!

Knowledge Pool is the Vedalken way for sure. Mirage Mirror works great with it! It turns into a black hole if you clone the pool during an opponents upkeep. Its also useful on its own.

Id be really curious to know what some of your experiences have been playing this deck. Maybe we could help each other out.
