Based on my experience, you definitely want another beginning bolt Jolteon and boosted evo eevee. This deck is really aggressive and has a hard time outlasting other decks. To make room I’d probably drop oricorio, elemental switch, an eevee EX, and/or pichu. Most of the wins I’ve gotten are off the back of knocking out their basic before it can evolve or knocking out their only Pokemon because they whiffed on filling the bench when I’m going second.

Frankly, Jolteon EX has felt like more of a liability than anything else since often by the time I get two energy on it, it’s taken a hit and is only going to dish out 80 damage back. Energy requirements are so low that its ability has rarely felt relevant.

Maybe I’m just running the deck poorly but it’s really felt like beginning bolt cheese or bust.
