i faced a garchop-altaria, that was my one win, zekeel, 5 drawn, zekeel w/ 2 mewtwo that were what beat me. i drew 5 prizes. my 4th round i faced an interesting deck running hoho ex, i drew 4 there. the guy with the hoho deck won the tourny, all the matches were random, that was how i faced a 3-0 at 1-2 myself.
i also think that you could run the abilityboars
+4 juniper
+3-2-2 abiliboar
+2 rare candy
-5 fire
-8 electric
like you said rayboar is a better deck but this would be fun to run, i know just 8 pkm and 52 energys was fun for me
