Generation 7 here we go! November 18th 2016.
While I've personally only been focusing on filling my Pokédex (which is about 60% complete at the moment [especially thanks to the 20th anniversary give-aways and wonder trade]), battling has especially difficult.
By the time Sun and Moon has arrived I hope to have completed my Pokédex and have some battle skills that can challenge you forum folk.
Considering each generation has added some new battle element, I can only wonder what this new generation will offer. Ultra evolutions? Na. Poké-fusions?
