Extrasensory > U-turn on Greninja; dealing with Mega Venusaur could be helpful.

King's Shield + Swords Dance Aegislash is horrible. It's walled easily and crippled by burn. You don't get how Stance Change works, do you? It simply lets Aegislash switch forms, which share the same EVs between one another. It's best to use offensive spreads on it as a result:
-Shadow Ball
-Shadow Sneak/Sacred Sword
-Iron Head/Sacred Sword/Pursuit
-King's Shield
Nature: Quiet
EVs: 244 HP/12 Def/252 SAtk
Item: Leftovers/Spooky Plate/Spell Tag/Air Balloon

or
-Substitute
-Toxic
-Shadow Ball
-King's Shield
Nature: Modest
EVs: 244 HP/12 Def/252 SAtk
Item: Leftovers

or
-Shadow Ball
-Shadow Sneak
-Flash Cannon/Sacred Sword
-Pursuit/Sacred Sword
Nature: Hasty/Naive
EVs: 4 Atk/252 SAtk/252 Spe
Item: Life Orb

or
-Swords Dance
-Shadow Sneak
-Shadow Claw/Iron Head
-Sacred Sword/Head Smash
Nature: Adamant
EVs: 252 Atk/4 SDef/252 Spe
Item: Life Orb

Fire Blast > Flamethrower on Charizard Y. It provides more power, while still being reasonably accurate. Put the last 4 EVs into either defensive stat; putting them in HP makes them even, making Charizard die to 2 Stealth Rock switch-ins.

Goodra's Rain conflicts with Charizard's Drought. Rain stalling is highly ineffective this generation because of the rain nerf to Drizzle. Instead, Goodra can act as a bulky Assault Vest sponge:
-Draco Meteor
-Fire Blast
-Thunderbolt/Earthquake
-Dragon Tail/Earthquake
Nature: Quiet/Sassy
EVs: 248 HP/252 SAtk/8 SDef
Item: Assault Vest
Ability: Gooey/Sap Sipper

Donphan is outclassed by Excadrill as a Rapid Spinner because the latter hits harder and has more reasonable Speed:
-Earthquake
-Iron Head
-Rapid Spin
-Rock Slide/Stealth Rock
Nature: Adamant
EVs: 252 Atk/4 Def/252 Spe
Item: Leftovers/Air Balloon
Ability: Mold Breaker

or
-Earthquake
-Iron Head
-Rock Slide
-Rapid Spin
Nature: Adamant/Jolly
EVs: 252 Atk/4 Def/252 Spe (Choice Scarf) or 120 HP/136 Atk/252 SDef (Assault Vest; Adamant only)
Item: Choice Scarf/Assault Vest
Ability: Mold Breaker

Ok. So if I wanted to go with a Physical Sweeper Aegislash I should just scratch King's Shield all togther and go with Iron Head or something?

I like your Goodra setup . I read that Rain was nerfed this gen so I was worried about that, so thanks for the new build.

Also, I totally would have gone with Excadrill first, had I known that he was in OU 6th gen. Guess I should have done a little more research on that one.

Lastly, should I have my Gorebyss pass to normally? I was originally going to pass to Charizard, but if there is a better option that I'm not seeing, I'd love to get some advice! Thanks again for your feedback!

 

[Nah]

For a purely physical Aegislash, use the last set Platinum posted. You can pass the Shell Smash boosts to anyone except Donphan really. Which is nice, because it allows for some flexibility during battles; you don't always have to pass to the same poke.

And Flamethrower really is a viable Fire STAB on Mega Zard Y. 80% accuracy isn't as accurate as you'd think Dragon Tail with its 90% accuracy misses way more than it should for me. The miss hax is strong in Pokemon. But play around with Fire Blast and Flamethrower, see which you like better.

 

[PlatinumDude]

And now I realized something wrong with your Shell Smash set: Gorebyss doesn't have Speed EVs to take advantage of the +2 Speed boost. Make the nature Timid with 252 HP/4 SAtk/252 Spe.

Yeah sorry, I didn't mean SpD. I also didn't mean that on Charizard and Greninja. They all are 252 Spe instead of SpD
