A very slight change on the deck Maddy featured a few days ago. I believe all I did was take his advice and add a second Sabrina. The results are pretty wild as I've won 8 in a row, beat many Zards. Not sure yet if Sableye or Absol are better partners but I think the extra damage of Sableye makes more sense late game (doesn't make it far enough to know) Serena, poke comm, x speed, poke balls all make this surprisingly consistent to get eevee into active. Repel/Sabrina keep umbreon hitting hard.
