Split Second
For each type of mana target opponent has in his or her mana pool, add that amount of mana to your mana pool.
Another card that exploits your opponents mana pool. This card punishes players for floating mana. I added the Split second ablity because this card would be fairly worthless without it (because who really floats mana without some way to use it). It also combos nicely with the other cards I have presented that toy around with your oppoent's mana pool.
Wording issue: I barrowed wording from Doubleing Cube, but basically the card is supposed to "copy" your opponents mana and add it to your own. Double Cube had the "For each color mana" .. 'Do this' wording so I mirrored that. Does it sound ok?
