It seems like a thread like this comes along every few months or so.
But I just love telling people about my shinies over 9000 times trololololololol.
I have a decent collection now. Most have been chained, I have over 60 chained pokemon, 4 were random encounters, 2 were bred via masuda method, 4 were SR'd and the rest have been obtained through a trade of some sort or event.
REs - Buneary/Lopunny, Magikarp, Sentret, Bagon/Salamence. The last two found by chaining but found in non-shiny patches.
SRd - Lugia, Ho-oh, Abra/Alakazam, Clefairy. Last two from LG game corner.
MM - Charmander/Charizard, Dratini
GTS - Eevee/Umbreon, Dialga, Gible, Relicanth, Latias <--- All Legit, they've been checked.
Trades - Machop/Machoke, Spoink/Grumpig, Kyogre, Miltank, Sinnoh caught Gyarados, Mightyena, Grimer, Turtwig, Piplup, Mudkip, Spiritomb, Ursaring, Zubat, VGC10 Eevee, VGC09 Milotic.
Events - Raikou, Entei, Suicune, Pichu/Raichu. Plus the Eevee and Milotic mentioned but they were traded for rather than obtained persoanlly.
Chained - Quite a lot. My favourites include Tyranitar, Metagross, Full Eeveelution set, Lairon, Vileplume, Furret with perfect attack, speed and naive nature, Ampharos, Camerupt with Quiet nature,no sync, Nidorino in Dive ball, Arcanine, Absol, Chansey, Ponyta and Ariados.
The Machop/Machoke and Spoink/Grumpig were traded to me from my finace who I helped chain them.
I also have one LoR Gyarados of course.
Oh I forgot. As of tonight I can add a shiny Deino to my traded shinies list =3 hopefully my own shiny Axew will hatch in my white version.
