If Eternal Flower Floette is unobtainable how will I fill the Pokedex?

Question

Or is it not needed to complete the Dex?

Comments

Wouldn't this ultimately be irrelevant?  It's either a "hidden" Floette variant (like the Pokeball and Fancy Vivillon patterns), or it's a Mythical Pokemon, and therefore doesn't count against the Pokedex -- you receive the Shiny Charm without the need of Mythical Pokemon.

Answer 1

Just use the Normal Floette. Eternal Flower Floette is just a variant of a normal Pokemon.
