Looking for the 20th anniversary events that I missed, which I think are:
Mew
Volcanion
Jirachi
Darkrai
Manaphy
Shaymin
Victini
Keldeo
Meloetta
I can trade:
shiny 5IV Adamant Crustle
shiny Bashful Gallade
shiny 4 IV Timid Milotic
L100 modest event Celebi (I don't remember which event, OT is GF, ID is 03016)
shiny 6IV L100 Noivern (I don't remember how I got it, it's legit though)
shiny 2IV Timid Pidgeot
shiny 6IV L100 Jolly Rapidash
event Vivillon (OT is GTS, ID is 00108)
shiny 6IV Jolly standard Dugtrio
Movie 14 Darkrai with Japanese OT but English name, so I'm unsure of its legitimacy (stats & summary page are otherwise normal though)
shiny 5IV Adamant Gale Wings Talonflame
shiny Amoonguss
Mew
Volcanion
Jirachi
Darkrai
Manaphy
Shaymin
Victini
Keldeo
