Tyranitar: Superpower, Stealth Rock. Doesn't matter what move but I'd prefer to keep Crunch.
Zoroark: Dark Pulse (over Night Daze) and Trick (over Focus Blast)
Riolu: Ice Punch (over endure)
Non-Shiny Jolly Metagross: Ice Punch, Thunderpunch and Trick. Meteor Mash is the only move that should still be there
Shiny Adamant Metagross: Ice Punch over Zen Headbutt
You can keep a copy of these. They're all flawless
