OK so finally we get an answer :)
By the way, when you click the button and it says "No Pokemon found", that is not "nothing happens". It's obviously looked for Pokemon matching those moves and not found anything. So it obviously did something.
The problem is basically that some of the slightly more obscure moves are missing.
- In Celebi's case, we don't have all the event moves, so that's something I will sort out when I can.
- In Empoleon's case it learns Steel Wing via TM in Generation 4, which for some reason is not included either.
If you find any other combinations that should work but don't, you can help me out by doing this:
- First double check each move to see exactly how the Pokemon learns it.
- If it's a basic level up/egg move/tutor/HM/TM for Gen 5, those should all be working fine.
- If it's a method not already mentioned, then let me know. Event moves and Gen 4 TMs have already been mentioned, and I just saw that Gen 3 move tutors and Gen 3 TMs don't work either.
Thanks!
