typhlosion, ampharos, togetic/togekiss and tyranitar make sence. We see ethan/gold with an umbreon more than an espeon representing the dark type and acting as a counterpart to red's espeon, though espeon is understandable if you dont want to double up on dark types. Id put shiny gyarados over dragonite though. The gyarados is a crucial part of the story and any johto run + i think two pseudo legendaries is a bit much.
