If I have Knowledge Pool and Teferi, Mage of Zhalfir on the table, can my opponent play spells off of Knowledge Pool, or does Teferi stop it because he reads "Each Opponent can play spells only any time he or she could play a sorcery." My friend says that because when you initially play a spell and it triggers Knowledge Pool to play a spell from exile, being allowed to play the second spell isn't at sorcery speed so you cannot play it. Is this correct? (instant game over as your opponent can't play spells as long as these 2 cards are on the table).
Knowledge Pool
{6}
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.
A second quick clarification I'd like addressed- Yavimaya Elder reads:
When Yavimaya Elder is put into a graveyard fro the battlefield, you may search your library for up to two basic land cards, reveal them, and put them into your hand. If you do, shuffle your library.
2, Sacrifice Yavimaya Elder: Draw a card.
question- when you sacrifice Yavimaya Elder to draw a card, do you draw the card first or search your library for 2 lands first? The confusion is, does the "draw a card" go onto the stack, then the "put into graveyard" hit the stack and resolve first, or is "draw a card" part of the cost of sacrificing therefor resolving at the time of the sacrifice before he is put into the graveyard?
9/25/2006: If an ability lets an opponent cast a spell as part of its effect (such as Isochron Scepter's ability does), that opponent can't cast that spell since the currently resolving ability is still on the stack.

For the elder, you search before drawing. The first step of activating the ability is to put it on the stack. Then after that you pay costs, including sacrifice, which trips the trigger. So the trigger goes on above, and will resolve first.
wow... that is so abusive for EDH. I am sorry but god that combo is soooo good and I didnt even see it until I read this post. I run Teferi as a general, thank you for pointing this one out to me.

Note, though, that spells may be cast as long as they are both cast at sorcery-speed, and not from your hand. While this may seem niche, it means that players may still cast their generals from the Command Zone.
How is it that your opponent would not be able to cast any spells please? Are spells cast with knowledge pool in play somehow no longer at sorcery speed?
Sorcery speed is a short hand for during your mainphase when the stack is empty.
If a knowledge pool is on the battlefield any spell that is cast is exiled as part of the triggered ability and the game attempts to give you a permission to cast a different spell whilst the ability is still on the stack resolving which Teferi, Mage of Zhalfir stops you from doing

Knowledge Pool exiles any spell cast from any player's hand, so the spell does not get to resolve. Then, Knowledge Pool has the player attempt to cast an other card exiled with it. However, Teferi stops that part for his controller's opponents, because "Anytime you could cast a sorcery" means "during your main phase when the stack is empty". The stack is not empty at that point since Knowledge Pool's ability is still there as it resolves.

Yes they could. The copy made by Riku's trigger is put on the stack, not cast, so neither Teferi nor the Pool will do anything about the copy.

Scientists have calculated that the chance of anything so patently absurd actually existing are millions to one. But magicians have calculated that million-to-one chances crop up nine times out of ten.
For that matter, Flashback seems to get around the combo as well. You're casting a spell, presumably during your main phase on an empty stack, and the Pool says it has to be cast from your hand, which Flashback is not.
Oh, I thought he was talking about playing a spell that is countering a spell with counters on it as it comes into play, but I see you guys were just discussing whether he was flashing a creature with flash in order to flash a flashback or just flashing a creature with flash but not needing flash in order to flashback a spell without flash.
I understand how this works; but not why. Normally I can cast sorceries out of the Knowledge pool despite the ability from the Knowledge Pool being on the stack. Why does Teferi's ability take precedence over Knowledge Pool, instead of vice versa?
There are also spells cast from the library like Panglacial Wurm.
Panglacial Wurm is a bad example in this case. There are very few situations where a player will be searching their library at a time that isn't part of a spell or ability resolving, and Teferi says you can't cast a spell while another spell or ability is resolving.
The only exceptions to this I can think of are replacement effects on drawing a card (Archmage Ascension, for example) but it's equally hard to get an effect that lets you draw cards during your main phase that isn't part of a resolving spell/ability.

I'm new so please don't be insulted by my newbishness.
I don't quite understand how the game mechanic would work between these 2 cards: knowledge pool and teferi, mage of zhalfir.
How is it that your opponent would not be able to cast any spells please? Are spells cast with knowledge pool in play somehow no longer at sorcery speed?

Can they break the lock with Riku?
For example, If I control Tefari + Knowlege pool
They control Riku. Can they play a instant/sorcery and make a copy and get around Knowledge Pool?
