How about an invincible Shedinja?
ability- Wonder guard
Spite- for extra stall filth
X-Scissor- STAB, criticizes chance
Shadow Sneak- STAB, priority
Toxic- to stall
skill swap- swap to shedinja.
Stealth Rock- helpful
Safeguard- to prevent status conditions
explosion- buffed by normal gem, doesn't affect shedinja
Ability- prankster--->Magic bounce
Swagger- to buff Shedinja
Safeguard- to block shedinja from status
Recover- to sustain
Sucker Punch- for those taunters
Simple, really. Skill swap Shedinja and Carbink, Bam. Shedinja now has Sturdy, so his one health keeps him alive. then Carbink can set up nd explosion to clear the enemy field, and you bring in Sableye to support and stuff, and then bring in another tank if one of these guys dies, I used Deoxys Defense.
P.S. I like your profile picture!
