Just a small nitpick:
For mega manectric, 252 speed and timid nature is really unnecessary in terms of what you outspeed. A more efficient spread would be
20 hp/252 sp. att/236 speed (timid). With this, you still outspeed everything you really need to (greninja, noivern, other pokes around base 130) and just get some more added bulk.
Just a slightly more efficient spread.
Also, I'd consider running Overheat over flamethrower. Two Overheats does more than two flamethrowers and idk why mega manectric would have to stay in longer than that AND be using a fire type move. Overheat helps nabbing the KO on things like Excadrill too, where flamethrower normally would let you down.
252 SpA Mega Manectric Flamethrower vs. 4 HP / 0 SpD Excadrill: 288-340 (79.5 - 93.9%) -- guaranteed 2HKO
252 SpA Mega Manectric Overheat vs. 4 HP / 0 SpD Excadrill: 414-488 (114.3 - 134.8%) -- guaranteed OHKO
On a separate note, if it hasn't been mentioned before, I'll say it now:
Your team is very weak to BU talonflame with taunt. Mega Manectric is the only thing stopping it, and it doesn't really even do that when talonflame can just roost to get rid of its flying type and then eat up a volt switch/tbolt.
252 SpA Mega Manectric Thunderbolt vs. 248 HP / 252+ SpD Talonflame: 276-326 (76.8 - 90.8%) -- guaranteed 2HKO
but half of that.
So 35%-45%?
Skarmory can take brave birds all day, yes, but a taunted skarm is just easy switch ins for whatever.
So I think you could look into hp rock maybe? I think it's rare enough that you don't have to worry too much but just wanted to point it out.
Everything basically looks good other than that. Hope I helped!
