You could just post this on your previous topic, there's was no need to star a new one. Still, I would take out Rotom. I would set Naganadel with Draco Meteor/Flamethrower/T-Bolt/Sludge Wave, holding either Dragonium-Z or Life Orb. Icy Wind on Greninja is kinda mee, holding life orb, you will need stronger moves (Hydro Pump, Dark Pulse, Grass Knot, Gunk Shot), as for Decidueye's item, try to taught it Shadow Claw, and holding Razor Claw, you will land crits more easy, (Same as Drapin, Razor Claw, Ability Sniper, and Cross Posion Night Slash).
