Sorry I have to tell you this but you have 3 Pokemon weak to Ice and Bug so I say that you should replace Zoroark, Torterra and/or Unfezant to cut down your disadvantage to Ice/Bug-types. Zoroark is special-based so Pursuit and Foul Play should be replaced. If your Unfezant has Super Luck than put a Scope Lens on it rather than a Sharp Beak as its strategy revolves around Critical Hits, Sky Attack should also be replaced as you don't want to waste a turn charging up. For Milotic, Dragon Tail and Hydro Pump should be replaced cos Dragon Tail forces you to move last while Hydro Pump is inaccurate. Outrage is not the best move for Hydreigon, you're better off with Flamethrower.

So yeah, a lot of negatives on your team that desperately need replacing

 

[Ho-Oh]

Adding to what Hikari10 said, Hydreigon also needs dark STAB, and Hyper Voice has no use at all, so Dark Pulse is muuuch better. ;x Also keep Draco Meteor, add Flamethrower as Hikari10 said and add Focus Blast to attack things that Flamethrower doesn't hurt.

For Zebstrika, just a note for the future, you have too many electric attacks (this isn't really good on any Pokemon since it wastes moveslots - except if it's a switching attack like tbolt & vswitch which is fine). Thunderbolt and Overheat are fine, but also go for Volt Switch to switch out and see what the opponent is going to use - and since it's fast and the nature suits, you'll be fine. As for Wild Charge, yeah nature isn't really helping you and it deals recoil damage. I guess since you can't really do anything with hidden power there's not much else you can do with your moveset right now :(

For Torterra, it's mostly physical, so Leaf Storm doesn't really help, nor does Giga Drain. Wood Hammer or Seed Bomb would work just as fine, and even better. Stone Edge = for coverage over flying & types and for the last attack it's up to you really. Leech Seed/Synethesis <-- for recovery or Rock Polish to speed it up can work fine.

Oh also, for replacements on Zoroark's sets, Flamethrower can work fine for coverage and Nasty Plot can also help to boost your sPA. If so, you'll need to use Dark Pulse > Night Daze. Aaand Punishment doesn't really help it, so you could always add Focus Blast for even more coverage for things that Flamethrower doesn't hit.

Also on Unfezant, Return = more powerful than Facade aka more useful for you if it really likes you.

On Milotic, Scald > Surf for burn chance to help your team against physical opponents. Also... actually Hikari10, Dragon Tail can help Milotic a lot since it's a Pokemon that's good at phazing but with this team it doesn't help since there's no Stealth Rock or Spikes, so you're right in that sense ;x Also Recover can be helpful if Scald does burn so you can last longer.

Just watch for too many attacks of one type on one Pokemon and you'll be fine, good luck :3
