What happens if I cast a spell while there are two Knowledge Pools out?
Asked by Sage25 14 years ago
While I found Knowledge Pool to be relatively easy to understand on its own, it feels a lot more complex when you have multiple copies out.
If I have 2 Knowledge Pool 's in play, I believe I choose the order when I cast a spell on my turn that they trigger and thus I can basically choose which one my spells are exiled to.
I'd like that confirmed and then- do i choose for my opponents spells? Or is it the last played? What's the ruling on each player having one?

- If multiple Knowledge Pools are on the battlefield, keep track of which cards are exiled by each of them. Whenever a player casts a spell from his or her hand:
-- If all Knowledge Pools are controlled by the same player, that player chooses the order in which the triggered abilities are put onto the stack. The last one put onto the stack will be the first to resolve.
-- If multiple players each control one or more Knowledge Pools, the active player put his or her triggered abilities on the stack in any order, then each other player in turn order does the same. The last ability put onto the stack this way will be the first to resolve.
-- The first triggered ability to resolve will exile the original spell, then the player who cast that spell may cast one of the nonland cards exiled by the Knowledge Pool that generated that triggered ability. The abilities of other Knowledge Pools will do nothing when they resolve, as the original spell will already have been exiled.

The "quick" answer is:
If you control all knowledge pools; You will choose the order they trigger onto the stack, regardless of who's turn it is.
If you and your opposing player controls a knowledge pool; Each player puts their triggers of knowledge pool on the stack according to active player to nonactive player order (APNAP).
If you and many opposing players control knowledge pool; Triggers start from active player and continued triggers are put on the stack based on turn order (aka clockwise around the table).
Whew...need a break.

Okay, the dreaded double knowledge pool. First, just to get the basic operation established, I'll do a quick rundown of what happens when Knowledge Pool comes into play.
First, you cast Knowledge Pool. Assuming that it hits the board successfully, it will immediately trigger and attempt to Imprint the top 3 cards of everyone's library. Then, whenever anyone casts a spell, Knowledge Pool will trigger. Once that trigger resolves, it exiles the spell and if it was successful, the owner of that spell can then pick one of the other spells exiled by it and cast it. It will put the new spell on the stack, both players will respond, and then it casts.
What it will not do is respond to copies of spells, such as with Pyromancer Ascension or Precursor Golem . It will also do nothing when anyone plays a land, as lands are not cast but instead put into play as a special action. Finally, if the pool is full of uncastable cards (such as lands or anything with illegal targets) then your spell will go in, but nothing will come out.
==================
Okay, I hope you're still with me. Down to multiple Knowledge Pool shenanigans. First, we'll start off with the easy one: One player owns multiple Pools. In this case, whenever a player casts, the owner of the Pools gets to choose the order in which they go on the stack, and since the exile is mandatory that means whoever it was will have to cast a spell from that pool. You can abuse this by stacking it so that your opponent always has to play out of the pool with the worst options, while you get the good ones.
Multiple owners of Knowledge Pool is a little trickier. Whenever a player casts a spell, the active player will place all of his Knowledge Pool triggers on the stack first, and then the non-active players will put their Pool triggers on the stack. Basically, in a 2-player game, this means you're always casting out of the inactive player's pool: The non-active player's pool is last in, which means it's first out.
In multiplayer games, if multiple people have pools, this means everyone will cast out of whoever's the furthest away from the active player's turn: In a 4-player game with turns going left, this means the person whose pool will actually 'win' the struggle is whoever is seated right of the active player.
