Hi all, it's been a long time since I've been on the forums. Pokemon Bank immediately rekindled my interest, so I'm back on the scene, and here's a new team I'd like some opinions on. As always, I accept ALL knowledge you can share, as I only want to improve. Thanks in advance for even viewing :)
So I'm new to making a single type team, haha. Ghosts aren't used all that much (From what I've seen), and they have enough variety to a)keep me from getting bored, and b)handle themselves well in different situations. Now, when making any suggestions, please remember that I would like to keep the ghost theme, and as far as I'm willing to stretch is psychic (if it looks evil enough) or dark. Alright, now, here's the team!

Banette (shiny) @Bannetite
Ability: Insomnia/ Prankster
252 HP/ 4 Atk/ 252 SpD
Careful
-Magic Coat
-Will-O-Wisp
-Confuse Ray
-Shadow Sneak
What an amazing improvement over Banette is it's Mega!? I always use this jerk to lead, and depending on the situation, start with a Magic Coat or Will-O-Wisp. Confuse Ray is a nice annoyance that helps prolong burn damage for those who want to try to tame the beast. Shadow Sneak is the only damaging attack I run in order to keep with the Priority theme. I will say that I'm surprised by the bulk Mega Banette has, and I haven't seen it faint many times yet in battle.

Golurk Leftovers
Ability: Iron Fist
252 HP/ 252 Atk/ 252 SpD
Adamant
-Power-Up Punch
-Earthquake
-Ice Punch
-Thunderpunch
The evil, hulking behemoth himself, Golurk. With an impressive attack stat for any Pokemon, let alone a ghost, I wanted to put him in here for dealing with specially defensive threats. If possible, I like to start off with one Power-Up Punch, to get a boost while doing a pretty decent amount of unresisted damage. From there, it's all situational. Earthquake for a good STAB that hits hard regardless of type, Ice Punch mostly in case of Dragons, and Thunderpunch in case a Water type attempts to come in and wash my big baby away. The Speed is an issue, and a Choice Scarf has crossed my mind, while replacing power up punch with something else. Thoughts?

Gengar Black Sludge
Ability: Levitate
4 HP/ 252 SpD/ 252 Spe
Timid
-Substitute
-Disable
-Shadow Ball
-Sludge Bomb
Behind Aracanine, Gengar has always been near the top of my list of favorite Pokemon. This set is pretty standard, I'll admit, but it still works so well. Obviously the first priority is to set up a Sub. Then Disable what ever attack was used against me, and set another Sub if needed. That usually causes a switch, and I go for a more straight forward approach from there. The choice between Sludge Bomb and Shadow Ball relies on the opponents type, or in some cases if I want the chance for a poison. I've played with Pain Split instead of Disable, but I'm unsure. I like the annoyances Ghosts can cause, after all.

Trevenant Leftovers
Ability: Natural Cure
252 HP/ 252 Atk/ 4 SpD
Adamant
-Horn Leech
-Shadow Claw
-Rest
-Sleep Talk
Sleep Talkers are fun for me. It's a bit of a gamble, I'll admit (We all know how infuriating it is to have a Pokemon try to use Rest when it's already sleeping!) but I like the recovery method. From there, I was looking for good Attack based STABs, so Shadow Claw was an obvious choice. Then I discovered Trevenant could learn Horn Leech! How cool?! I never played with him in game (I use a super Gourgeist), so I was surprised. It really adds to his longevity, and does decent damage. Really digging this guy.

Chandelure Life Orb
Ability: Infiltrator
252 SpA/ 4 SpD/ 252 Spe
Timid
-Fire Blast
-Shadow Ball
-Psychic
-Hidden Power Electric
The lighting fixture that could blow a hole in the side of a tank, Chandelure! Infiltrator and Life Orb should reveal the usage of this beauty. Literally, nothing can get away without being hurt a little by this. Fire Blast because I don't care enough about accuracy in this case, when there is the potential for so much more damage over Flamethrower. Shadow Ball as the obvious other special STAB. Psychic is here for big ol' fighting types, specifically Conkeldurr. Hidden Power Electric is here in case of emergency. I would rather not have him out if I'm starring down a Water type, but if I must, there it is.

Aegislash Leftovers
Ability: Stance Change
252 HP/ 252 Atk/ 4 SpD
Adamant
-Sacred Sword
-King's Shield
-Swords Dance
-Shadow Sneak
Again, I'm out of the loop, but if this isn't the standard set for Aegislash, I would argue that it should be. Sacred Sword is here because it's crazy powerful now, and a STAB Steel just didn't feel necessary. King's Shield because it is one of the best moves I've seen. It's downright dirty. Swords Dance is here because knowing you can just stay in Defensive and boost your attack straight to God's doorstep is a nice feeling. Shadow Sneak is a decent enough Attack based STAB, that also has the priority.
Well there are my evil friends for you to see and rate! Please let me know your thoughts and give me any advice you might have!
