So I've been using this team online, and its been working fairly well, but wouldn't mind a second or third opinion before registering the team for the April Friendly.
Reuniclus @ Life Orb
Magic Guard
Quiet
252 HP, 252 SATK, 4 SDEF
-Trick Room
-Psychic
-Shadow Ball
-Focus Blast
This is usually the Trick Roomer I'll lead with. Nothing too out-of-the-ordinary here. Great coverage and solid defenses to back a great SATK.
Slowbro @ Wise Glasses
Oblivious
Quiet
252 HP, 252 SATK, 4 DEF
-Trick Room
-Psychic
-Scald
-Fire Blast
The other TRer. Oblivious lets you set up TR through a Taunt, Reuniclus's Focus Blast is usually more relevant than Fire Blast, but against the teams Fire Blast is good against, Slowbro can get the nod for the lead.
Ampharos @ Ampharosite
Static/Mold Breaker
Quiet
252 HP, 252 SATK, 4 DEF
-Thunderbolt
-Dragon Pulse
-Focus Blast
-Signal Beam
Mega Ampharos's obscene SATK works great under an active Trick Room. Really that's it.
Ferrothorn @ Expert Belt
Iron Barbs
Brave
252 HP, 252 ATK, 4 DEF
-Stealth Rock
-Gyro Ball
-Power Whip
-Explosion
Ferrothorn sometimes gets to lead instead of Reuniclus or Slowbro. Stealth Rock for Charizard, Volcarona, and Talonflame. Gyro Ball for Gengar, Greninja, and Noivern. Power Whip for Tyranitar and other slow Pokemon. Explosion helps round out the set.
Flareon @ Muscle Band
Flash Fire
Brave
252 HP, 252 ATK, 4 SDEF
-Flare Blitz
-Bite
-Double-edge
-Quick Attack
Flareon's the newest member of the team. He's currently replacing my Arcanine as Arcanine's not in the Kalos 'Dex. Not having access to Wild Charge is a bit of a pain, but Flareon's been doing a decent job as an Arcanine. The main trick is to bait a fire attack with Ferrothorn then switch into Flareon for gigantic Flare Blitzs. Quick Attack for revenge kills and Bite for coverage.
Snorlax @ Rocky Helmet
Immunity
Careful
252 HP, 156 SDEF, 100 DEF
-Curse
-Rest
-Sleep Talk
-Body Slam
I believe this is a fairly standard Curselax set. As long as the rest of my team can take out the Ghosts and Fighting Pokemon on the other side, Snorlax will save me if I get in trouble. Immunity saves me against needing to rest early due to Toxic, allowing me to get as many curses in as possible before resting.
