Does the description of the card and the effect table really have to be completely accurate? 
I ran out of room on the card...
Also, this card wouldn't that good for FG farming because the process would be long and boring, you could perhaps get 2-3 games finished in the time you get one finished with a deck that utilizes this deck.
I prefer the way this card works, gives a reason to upgrade this card.
Unfortunately, that's how all of the other card ideas are.
If you don't have enough room on the card, you could a) edit the description completely to find another way to fit all of your information with the correct font and font size, and b) you never know when there's going to be a random player who will ask the inevitable question of: "Hey, did you update your card? How come the description in the table isn't the same as the one on the card art?"
(See my 'Description Workshop' (
http://elementscommunity.org/forum/index.php/topic,9851.0.html) if you really want to figure out a way to include the 'Rounding Down' part in the card)
As for how 'the card works', I guess I can agree with that. The upgrade to me just feels... not so epic in comparison to the other upgraded
cards. I mean, Holy Flash is practically free and can be splashed in any deck, Miracle receives a huge cost reduction of 3
quanta, etc. This is one of the few cards that actually has an INCREASE in a quanta cost to justify the increased effect, but I feel that if an opponent deals an average of 30 damage per round (that's a pretty decent amount of damage) with his creatures, dealing 15 damage back rather than 10 just doesn't feel very 'upgraded' to me.
Edit: Also, what ddevans96 said.
