SM OU First team, suggestions?

[Geode1204]

Accelgor @ Mago Berry
Ability: Unburden
Shiny: Yes
EVs: 248 HP / 8 Atk / 252 Spe
Jolly Nature
IVs: 0 Atk
- Encore
- Toxic Spikes
- Spikes
- Substitute

Substitute, Encore, spikes, just a hazard setup mon.

Volcarona @ Buginium Z
Ability: Flame Body
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Quiver Dance
- Flamethrower
- Bug Buzz
- Giga Drain

If given the chance to set up with quiver dance, this thing can sweep a whole team

Greninja @ Fightinium Z
Ability: Protean
Shiny: Yes
EVs: 4 Atk / 252 SpA / 252 Spe
Hasty Nature
- Ice Beam
- Gunk Shot
- Dark Pulse
- Low Kick

Really just used as a late game mon to kill whatevers next, gunk shot helps with fairy types. Not sure if should include water shuriken


Blacephalon @ Choice Specs
Ability: Beast Boost
Shiny: Yes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Fire Blast
- Shadow Ball
- Pain Split
- Trick

601 SPA to begin with and decent speed, a really fun mon to use, if defensively not the best

Serperior @ Leftovers
Ability: Contrary
EVs: 56 HP / 200 SpA / 252 Spe
Timid Nature
- Leaf Storm
- Hidden Power [Fire]
- Substitute
- Glare

I! LOVE! CONTRARY! Leaf storm boosts SPA insanely and hidden power fire deals with pesky steel types and sap sippers.

Alakazam-Mega @ Alakazite
Ability: Magic Guard
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Dazzling Gleam

Hi, welcome to Smogon! I'm locking your RMT for the time being as the forum rules require that you provide at least 3 lines of descriptions for each Pokemon to explain their roles. Please read the rules carefully and take a look at Team Showcase to see the level of detail we require. PM me with updated descriptions and I'll be happy to unlock this.
