No Zangoose? Zangoose is insanely powerful after the Toxic Orb boost, both as a cleaner and as a wallbreaker with SD. I'll just show you some calcs for the SD set:
+2 Toxic Boost Facade vs. 252/252 Impish Eviolite Gligar: 73%-87%, easy 2HKO
+2 Toxic Boost Facade vs. 252/252 Bold Slowbro: 90%-106%, possible 1HKO, definite 1HKO with SR up
+2 Toxic Boost Night Slash vs. 252/252 Bold Cofagrigus: 60%-71%
These are three of the sturdiest walls in the game-and are all 2HKO'd. Not even Swords Dance Heracross can do this, as he is walled hard by both Cofagrigus and Gligar(Stone Edge does 36%-43% to the mentioned Cofagrigus when Heracross has 252 attack ev's and a neutral nature, and Stone Edge does just 29%-35% to the mentioned Gligar). Even if the Heracross has Guts activated, it still does just 37%-43% to standard Gligar, so even if it hits max damage twice after Stealth Rock the Gligar can just Roost off the damage and stall him out until the burn or Toxic damage kills him.
That's not all Zangoose can do though-he makes a great cleaner as well. Quick Attack is now one of the most powerful priority attacks in the metagame, and Facade is still ridiculously strong(210bp after STAB-it gets boosted by status). Combine this with Close Combat and Night Slash/Shadow Claw, and he is very difficult to stop if Spikes are up and the opponent's team has been substantially weakened.
