I want to build a deck around this guy for multiplayer. Just a bunch of zero-mana and otherwise cheap spells (Memnite, Ornithopter, Mishra's Bauble, Urza's Bauble, Gitaxian Probe, Manamorphose, maybe some ramp spells and tutors, and four copies of this guy. Put down Pool after Pool and enjoy defeating your enemies with their own best spells, which you cast for free, by the way.
Multiplayer is just more fun when one of the decks is designed to abuse Knowledge Pool. 5/5 for multiplayer.
As for its capabilities outside griefing in multiplayer, eh, I don't really know. I'm waiting for someone to do something cool with a Knowledge Pool deck in a tournament, but it's a bit too random to expect to win consistently. That doesn't really matter to me, anyway, because of the aforementioned multiplayer hilarity.

EDIT: Thank you, Gelzo, for reminding me of the Pact cy... (see all)

So... am I right in assuming that Cascade will trigger TWICE if I cast another card after the one with Cascade (to grab back the original)? 6 = Etherium-Horn Sorcerer - Cascade - tuck under Pool - 1 = Brainstorm - tuck&grab Sorcerer -Cascade! Oh Chaos, how I love thee, let me count the ways: Scroll Rack - Possibility Storm - *insert favorite combo here*

Hey look, a typo in the Oracle rulings.

"If multiple Knowledge Pools are on the battlefield, keep track of which cards are exiled by each of them."

That should read

"If multiple Knowledge Pools are on the battlefield, QUIT WHILE YOU STILL CAN. RUN. GO. FLY, YOU FOOLS!"

Did I miss something or did no one else mention the Pact cycle?

Intervention Pact, Pact of Negation, Pact of the Titan, Slaughter Pact, and Summoner's Pact. You get to grab something out for free at instant speed, and you fill the pool with cards that make your opponents either pay extra mana or lose.

The first card I've ever seen go undrafted on grounds of no one understanding what in blue hell it does.

To clarify how this works, thanks to an official article:
1. Any spell cast by any player from their hand does not resolve. Instead, it gets exiled to the pool. This counts as imprinting that spell for later use. If the spell gets countered or otherwise removed from the stack in some manner before the pool trigger resolves, the spell is not imprinted and the player doesn't get a freebie replacement from the pool.
2. Instead of the spell a player casts from their hand, they get their choice one of the spells currently imprinted onto the pool. They can choose a card owned by either player.
3. This does allow for breaking of the normal timing rules except where the spell has an explicit restriction on when it can be cast (e.g., only during the combat step.)
4. (This last one is my interpretation but I'm 99% sure this is correct.) A card imprinted to the pool can only be used once, because when you cast the card from exile it gets moved from exile to the stack and is thus no longer imprint... (see all)

I see some people using it to play creatures for nearly no mana and such, but I gotta ask, Why has no one thrown out the Idea of a deck full of instances with this? You wait for an opponent to play something you want, throw down a instant and then grab there best cards off the pile before they have a chance to play a second card to retrieve it.
