Well the event Pokemon I would allow for special shiny Pokemon requests are as follows:
10th Anniversary Events
Berry Glitch Fix Events
Pokemon Box Events
Toys R Us Events
Pokemon Ranger Events
Pokemon Battle Revolution Events
These would be about the only ones I would trade for shiny Pokemon. However depending on your choices I may require a few shiny Pokemon for one event.
Also the choices aren't limited to just these there are some others I would have no problem trading, but those would require multiple shiny Pokemon. The only ones I would say to avoid are the NFT events and GOO events. Since all of the NFT events were personally requested to be listed as NFT and the GOO events are rare or very rare which is what GOO is for. I have all of the abbreviations listed on the first post of my shop for their meanings.
I also have some other events that aren't listed on the shop yet, not many but there is few that aren't listed yet.
If I would need to request a few more shiny Pokemon I can list those for you as well if you would like. I also have a load of regular egg move Pokemon (over 1 dozen) that I need shiny version RNG of. If you would like me to trade you some of these I could count those towards some of the events you would like.
Okay I have figured out some more egg move Pokemon (all male again):
1) Teddiursa (must be male): Fake Tears and Double-Edge
2) Nosepass (must be male): Double-Edge, Explosion, Magnitude, and Rollout
3) Spoink (must be male): Amnesia and Trick
4) Cacnea (must be male): Low Kick and Dynamic Punch
5) Igglybuff (must be male): Wish, Present, and Last Resort
6) Cleffa (must be male): Amnesia, Belly Drum, Present, and Substitute
7) Chatot (must be male): Encore and Nasty Plot
8) Abra (must be male): Fire Punch, Ice Punch, Power Trick, and Thunder Punch
Are you able to obtain these shiny egg move Pokemon?
