>>15951380Hydreigon should drop Flamethrower and Dragon Pulse for Fire Blast and Draco Meteor.
And consider breeding a Naive/Hasty/Rash/Mild Hydreigon with Head Smash. Bitches don't know 'bout dat Head Smash. If recoil is too scary, then forget Surf and give it U-Turn for scouting shit, especially if you decide to Scarf it. Slap an Orb or a Scarf on it, and you've got a nice, speedy nuke on your hands. Just don't run Scarf if you're bad at prediction; ideally you'll want to consistently kill things each time you switch in,
Greninja should be running Life Orb, Focus Sash, or Expert Belt, or a King's Rock if you're an asshole. Choice items are counterproductive on it, and you have no bulk.
Talonflame should probably hold a Choice Band. If you want a Flying-type staller, use Poison Heal Gliscor.
Imposter Ditto: Scarf it, Sash it, or maybe Orb it if you plan on copying Megas. Scarf and Sash are your best options.
Mystic Water is actually a good option for Azumarill. Keep using that. Replace Double-Edge with Brick Break or Waterfall, though.
Your team has two Water types and your Hydreigon has Surf. Venusun is entirely counterproductive; dump it for Gliscor or a tanky Steel type. A hazard setting Ferrothorn is a good idea, since it'd make for a great opener. Pity about those Rocketburds...
MegaKhan and Aegislash would also fit better over Venusaur.
