Why waste a space on Pipikek considering that only Trumbeak is used? They didn't care about Toucannon, so really just don't waste the space TBH.
Mimikyu is a staple for non-gx or gx non-ability decks (that don't use Green's already). You are locking your opponent out of any use of their abilities through the use of a single shrine of punishment (for Pikazekrom and Mewbox), or Roxie + Weezing. Hell, you can use Giratina for localized ability negation.
Cottonee is a fantastic additional attacker for Lost March, seeing how big ReshiZekrom is going to be in Cosmic Eclipse. Too bad about no double colorless but we still have counter gain.
The Eevee support is really cool. They want you to play the deck by using all the eeveelutions, and a single Eeevee of these setups your entire bench for that purpose. I "almost" don't miss Energy Evolution anymore. Too bad evolution decks are a bit boned come SWSH unless they give us ways to setup turn 1 easily.
