I wouldn't mind doing this at all. You can only get Koffing at Pokemon Mansion, by which point you have PLENTY of cash for Revives. 10 Revives for evolving really isn't all that much (even less if you just explode on everything in Blaine's gym and use the Pokecenter), and considering you have only two badges to get after you find it (Volcanobadge and whatever Giovanni's is), that's not much of a penalty. How hard is it really to use Selfdestruct and then a Revive? I'm sorry, but that's being REALLY touchy over something that isn't much of a deal at all. Compare: use Selfdestruct/Explosion ten times, or kill an Electric-type with a double-HM Prinplup with no Water moves. I just finished a playthrough on Blue, you want me to do this with you?
