Assault Vest prevents Tyranitar from using status moves like Protect. Specially defensive Tyranitar should look like this:
-Stone Edge/Rock Slide
-Crunch
-Pursuit
-Fire Blast/Stealth Rock
Nature: Sassy/Careful
EVs: 252 HP/4 Atk/252 SDef
Item: Assault Vest/Leftovers
Ability: Sand Stream
Even though Doublade has monstrous physical bulk with Eviolite, its special bulk is still terrible. Aegislash is still better because it has equally good Defense and Special Defense:
-Shadow Ball
-Sacred Sword/Shadow Sneak
-Iron Head/Shadow Sneak
-King's Shield
Nature: Quiet
EVs: 240 HP/252 SAtk/4 SDef/12 Spe
Item: Leftovers
or
-Shadow Ball
-Shadow Sneak
-Sacred Sword
-King's Shield/Iron Head
Nature: Quiet
EVs: 252 Atk/252 SAtk/4 SDef
Item: Leftovers
or
-Swords Dance
-Shadow Claw/King's Shield
-Shadow Sneak
-Sacred Sword
Nature: Adamant
EVs: 240 HP/252 Atk/4 SDef/12 Spe
Item: Leftovers/Life Orb
or
-Swords Dance
-Autotomize
-Shadow Claw
-Sacred Sword
Nature: Adamant
EVs: 88 HP/252 Atk/168 Spe
Item: Leftovers
or
-Autotomize
-Shadow Ball
-Hidden Power (Ice)
-Sacred Sword/Iron Head/Flash Cannon
Nature: Rash/Modest
EVs: 88 Atk/252 SAtk/168 Spe
Item: Life Orb/Weakness Policy
Togekiss appreciates its Leftovers recovery, even in sand, since it can wear itself down without Leftovers, even with Roost.
Meowstic is absolute Taunt bait. Klefki, Whimsicott and Sableye make better Prankster users, IMO, because the former takes hits better than Meowstic, while the latter two are a lot more disruptive:
Klefki:
-Reflect
-Light Screen
-Spikes
-Foul Play/Dazzling Gleam
Nature: Bold
EVs: 252 HP/152 Def/104 SDef
Item: Light Clay
Ability: Prankster
Sableye:
-Will-o-Wisp
-Taunt
-Recover
-Foul Play/Confide/Knock Off
Nature: Calm/Careful
EVs: 252 HP/4 Def/252 SDef
Item: Leftovers
Ability: Prankster
Whimsicott:
-Encore
-U-turn
-Memento
-Switcheroo/Stun Spore/Taunt
Nature: Impish
EVs: 252 HP/252 Def/4 SDef
Item: Lagging Tail/Leftovers
Ability: Prankster
Blastoise's niche is a bulky Rapid Spinner. You're not using that niche at all:
-Water Pulse/Scald/Hydro Pump
-Dark Pulse
-Aura Sphere/Ice Beam
-Rapid Spin
Nature: Modest
EVs: 252 HP/252 SAtk/4 SDef
Item: Blastoisinite
Wish support would be good for the rest of the team, especially for Blastoise and Tyranitar. Sylveon can do that:
-Wish
-Protect
-Hyper Voice
-Heal Bell
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Pixilate
Thanks, this looks really good, It was only a team I chucked together earlier.
However, with the Aegislash wouldn't I be better off having Iron head, purely to eliminate any fairy threats? They were causing me big problems, which is the main reason I brought the move in, and that seems to have helped.
I'm thinking of maybe going: Shadow claw, Sacred sword, Kings shield, Iron head. Does that sound viable?
Edit: My bad, just realised you did actually have a build with Iron Head, thanks again!
