Krark's Thumb anyone?
It could even result in 1000 colorless mana. Or 20 for a Fireball.

@bijart_dauth: Mana abilities (abilities like tap: add one mana) can used faster than instants, they occur outside of the stack. This rule probably is so that you don't use this as a mana ability, for whatever reason.

The reason it says "only as an instant" is because you can undo mana abilities if you realize you can't pay for a spell. I can declare casting Emrakul, the Eons Torn and then use mana screw's ability to generate mana if it were a mana ability. If I don't hit 15, then I can undo the abilities and try again. That would suck.

You don't have to win 1,000,000 flips in a row to play Gleemax with this. You can afford to lose sometimes, as long as you earn back the lost mana and never get down to 
.
This card is very powerful, or would be if it were played in a real set. With the Thumb, it becomes one of the cheapest infinite-mana combos around. And I do mean infinite.
This minigame is covered by the Gambler's Ruin Theorem, which gives a very simple formula for the probability that you will eventually reach X mana given that you currently have Y. The formula is X divided by Y. This means that, starting from 
, you have a 1/1,000,000 chance of being able to cast Gleemax. And a very tolerable 2/15 chance of getting Emrakul out on the second turn, though with rather a lot of flips.
That's the formula for a fair coin. The Thumb essentially replaces that with an unfair coin (one which wins 75% of the time), which complicates the maths somewhat. But you stand to win far more than you lose. In fact, starting at ... (see all)

Now I'm waiting for an Un card named Mana Flood.

Use this card too much and you might end up, um...
What do they call not having enough mana again?

I can't believe no one has mentioned Chance Encounter! Every win is a luck counter and two more chances! Sounds like a carnie game pitch, come to think of it...

Anyone else notice that the color wheel is out of whack in the art? Black needs to be moved to rest between blue and red.
I'm not OCD.

This is one of a very few number of Un cards that could work with no problems outside of a Un set.
