. Spend some time building and thinking the direction of the build I wanted to go and I decided to go hazard spam offense. So I decided to go Lando+greninja for hazard setters. Offense doesn't really have solid spike users so I went with ninja. How to use the ninja is pretty cool gunk shot to hit fini which they like to switch in on ninja all the time and next option I went Hp electric because Mantiane can switch in too. I know hp electric can hit fini but allows me to hit other things too like bulky waters like mega dos and normal dos. After I decided to go pheromosa. Reason pheromosa with greninja hitting it's common checks it also hits pheromosa checks too and weakening them. I went with Adamant scarf because you don't need a boost in speed because you speed the whole meta with a 601 speed stat so that mean you out speed weather sweepers too and with greninja+hazards spam pheromosa has high potential to sweep teams. Next I went with mind plate Lele. Reason I went with mind plate it can bluff a choice item also 1.2 (item)+1.5 (terrain)+1.5(stab)+90 psyshock lets you 2hko Chansey. Taunt to keep hazards up and shutting down defensive Pokemon. Lele is amazing support for Pheromosa too because it doesn't allow priority which means pheromosa doesn't have to fear anymore. I need psychic,Draco, and greninja switch so I went with AV Magearna. This thing is an amazing mon it can switch in on too so many things and can beat all Tapus if healthy enough. Last but not least I went Zard X because I was still weak to scizor and Char Y (char Y is crazy good because of the lack of Y checks in teams) also char X can sweep though teams and with spam makes it easier and with greninja with gunk hitting fini I don't really have to worry about misty terrain weakening dragon moves in the long term battle.  Oh forgot Lando. Lando is for rocks and Yache to lure in koko so magearna doesn't have to take a hit always. Because gren+koko overwhelmed it.  So pretty much the goal is get hazards up and use magearna+Lando to let pheromosa and your threats in easy. Get hazards up to weaken your opponent's team too or go for game with Zard X.
