Nice list!

As for mistakes, Flygon, Kirlia, Wailmer, Breloom, Groudon, and Salamence have appeared in eps. Have a Stammer mentioned the first three, but as for the others:
Breloom was in the one where Flannery was introduced, and it showed her grandfather Muro the former Gym leader kickin' with his Typhlosion, up against Dodrio, Vileplume, and Breloom.
Groudon was in a cut scene in the Team Magma/Ocean Museum ep, where they talked about the legend of Groudon lurking deep underground below sea level.
Salamence was in the Bagon ep, there were several cut scenes where Mitchell was talking about a Salamence trainer and how he wants one, and it showed a Salamence in action.

Other than that, it's accurate
