Technically I -can-, since I have a Bold HP Electric spread abused, and a flawless Calm one (but the frame is like 5000+, while the Bold HP electric is on 4 lol .-.)
Only issue is I've never caught a Feebas before, or tried attempting to fish for it...so...yeah o.o If there's a summary of how it works in HG/SS or Plat I wouldn't mind reading it and giving it a shot.
I'll have to look at your thread but I might just take it on simply for the challenge. Thought I've kinda semi-retired/taking a break from RNGing in general and I have a bit of a priority/project list going on.
