Teferi, Mage of Zhalfir

= you win.


1-Your opponent plays something
2- knowledge pools first ability goes on the stack removing the spell.
3- the second ability goes on the stack
4- your opponent can only play spells when they can play sorceries (per teferi's ruling, the stack must be EMPTY)
5- since the stack is not empty they cannot play anything.

I played two of these in my Pyromancer Ascension deck. The idea is, you cast a spell, then copy it with the Ascension, then pitch the original to the Pool and cast a new spell. If it's an instant or sorcery, copy it too. So, your stack just from casting an instant or sorcery is:

Top: Fetched spell copy (if instant or sorcery)
Fetched spell
Pitched spell copy

Allows more bang for your buck.

On the other hand, I've been cursed out for playing this card.

It would have probably been more suited as a mythic, considering the unique quality of the effect and its limited desire for use / borderline hatred among spikes.

Also, considering the lore, the Knowledge Pool is known to be the source of Vedalken Serum at the heart of Lumengrid (Known as the Seat of the Synod to others), a source of great power (Beacon of Tomorrow), which could be found no where else on Mirrodin. So really, considering its historical significance to the block and for practical purposes (I mean, who really wants multiple instances of this card going off?) , it should have been legendary.

Its interesting to consider what has happened to it considering the recent "Changing of the Guard" of what was once the Vedalken's quicksilver sea- What ghastly scientific secrets (Turn Aside for flavor reference) that were divulged to the Phyrexians upon their take-over in the depths of its iridescent pool is anyones g...

So how are cards that have a Mana cost of X treated? It's 0 as usual?

And how are cards with other costs such as Rebound, Kicker, and Mutli-Kicker treated?

I'm a returning Magic player and a bit confused with the stack rules. When does Knowledge Pool swap out the card that was cast? The moment it is played? or can you still respond to the card that was played before it is swapped by the Pool for something else?

To illustrate: there is an Emrakul and a Counterspell in the Pool. My opponent casts Giant Growth, intending to take the Emrakul out for himself. Can I respond with an instant like Preordain, pull the Counterspell, and counter the Giant Growth before it pulls the Emrakul? Or for that matter, can my Preordain just pull out Emrakul?

edit: sorry, Preordain is a sorcery. Let's say it's a brainstorm then.

I've got the answer to my question btw. Yes on all counts. I can pull the Counterspell and counter the Giant
Growth. I can also pull Emrakul instead.

Everything you need to know about Knowledge Pool:

Okay, a spell sharing deck

This + Eye of the Storm + Hive Mind

since with Knowledge Pool, you are casting cards, they will flow to Eye of the Storm, and then through Hive Mind.

When you figure this card out, it's actually really cool! Great fun in multiplayer!
