Oh come on, this series had some pretty good ideas like windmill! I like it, it's sort of like a fusion between Pandemonium and Chaos Power/Chaos Seed. Judging from the effects of those cards, I'd say this card appears balanced.
haha, cheers. I'm not so much complaining about the ideas and mechanics, but I do sometimes feel I'm pushing it with the names and corresponding imagery lol.
As I mentioned somewhere, it's these things in nature which have given me the idea for the cards (wind -> energy, compost -> help with life from dead life, drought -> no energy/crop) so in that sense it's cool, and obviously the name can be changed to something more mythical/fantasy based easily, that's not the crucial part, the mechanism, cost etc are the crucial bits.
Should I do a poll as to attack can go below 0 or not, or are there some very strong opinions why it should/shouldn't? I know az4rel says yes. My reason for not is that I feel an evolution where you gain/loose some attack/HP isn't quite on the same level as "antimatter" and being able to heal with an attack :s
