Not all of them, but the ones on my current OR/AS run that I've been very VERY happy with.
Monte-mon because he was given to me by my rival (yes! I have a Pokémon rival, this delights me to no end!); Monte-mon was frickin' MVP when it came to the OR cover-mon fight (you know who I mean). He stood up to said Primal-mon, who was not only his Type better but UBER powerful at that and Monte-mon lasted a very long time. I'm beyond impressed. Monte raised him well.
Gryf should be obvious. The Beast is my newest baby, named after one of my Hubby's charas.
And then there's KKG. Good frigging Lord, Monte-mon's owner had a hell of a time bringing this one down during our second rival battle. IIRC, KKG even overpowered his precious Umbravia (tho I could totally be misremembering). Best Recover battle ever, snerk.
Yeah, I'm missing two but these four have been my core. Color incoming.
