~this~ deals X damage to target player, where X is the amount of mana in their mana pool.
Draw a card.

Awful card.

Most of the time mana isnt in a player's mana pool at a time when this could be cast. Even in the rare instance that occurs, the amount being floated is extremely minimal.

[Jacob Orlove]

Narrow cantrips for one mana are fine cards.

[Matt]

Yeah but this basically has to be rare and that's no good.

[Machinus]

I think it's a neat idea, but it is rarely going to do damage unless the ability is modified somewhat. This is only good against combo decks that make lots of mana and have to cast sorceries.

[dandan]

Dump the cantrip and make it 'in all mana pools' and you have yourself a wacky Lava Axe. It might allow you to double Fireball or it might cause you to take X mana burn!!

The cantrip version is fine as a cheap cantrip and a very narrow card.

I know that this is a different card, but I just get the feeling that this idea would inevitably evolve into [card]Parallectric Feedback[/card].  It has been pointed out that this card is a little bit weak and I think that ultimately, it would end up keying off something's converted mana cost in order to get some more mileage out of it.

[Matt]

If you just want to punish players for floating mana, you could make an enchantment or artifact that said "whenever a player plays a spell, empty all mana pools" which would not only make it hard to float mana, but would let you ruin their attempts to float mana by playing an instant of your own.

Or "mana abilities each player controls can't be played whenever that player could play an instant," which is a lot uglier, but exactly removes players' ability to "float" mana - with that in play, you can only play mana abilities during the announcement of a spell or ability, and (I think) only to pay for that spell or ability, or whenever a resolving stack object asks for a payment (Mana Leak, [card]Mundungu[/card]).

Since option B is ugly, less useful, and may not even work, I would go with my first suggestion.

[Anusien]

What about making this an interrupt?

I wouldn't mind making it more expensive (1R, or 2R with cantrip) and keying it off the mana in your mana pool.  Ephraim is right about the Parallectric Feedback, but you can sort of mirror Glissa this way.

... you can sort of mirror Glissa this way.

I've actually been working on a double cycle of Glissa mirrors, should be posting in the next week or so.

I like where Matt was going with the enchantment.

Whenever a player plays a spell, empty all mana pools and each player takes X damage, where X is the amount of mana emptied.

There's got to be a better template for that. I'll do some digging.

I already tried creating a card just like that and after extensive discussion, I don't think we ever came up with a way of of making it work that fit within the rules.

[Harlequin]

You could Forgo the mana clearing and just have it deal damage. 

"As an additional cost to playing spells, the spells controler must pay X life where X is the ammount of mana in that players mana pool after all mana costs have been paid."

It kinda... messes with the ability for players to choose the order in which they pay costs...  I'm not sure its worth the headache of mapping out all possible ripples this type of card will cause with the rules.  Certainly anyone who has to play with or against this cards must CLEARLY know exactly how the rules dictate "paying for a spell or ability."  It would be a judging nightmare.

[netherspirit]

"As an additional cost to playing spells, the spells controler must pay X life where X is the ammount of mana in that players mana pool after all mana costs have been paid."

If you wanted to do that but keep it simple, why not just have something along the lines of:

"Whenever a player plays a spell they lose life equal to its converted mana cost"

But then it really does start evolving towards Parallectric Feedback.
