I currently have all the silver prints in the Battle Frontier.
I just lost my streak of 34 in the Battle Castle. Which was awful because I ranked up 3 times.
I also currently have a streak of 90 in the Battle Hall And a current streak of 27 in the the rest of the Battle Facilities.
The hardest one is of course the Battle Tower where I need to get my 100-Streak.
This is the team I use for the most part:



Gengar@Focus Sash (Timid)
EVs 252 Sp. Attack/252 Spd/4 HP
-Shadow Ball
-Focus Blast
-Thunderbolt
-Explosion
This move set is great especially with a Focus Sash.
I can just attack with powerful moves and 1HKO or 2HKO most of the time.
If I get hit with a move that even only does half damage I use Explosion right away. The only down side is Focus Blast's unreliable accuracy.

Weavile@Chople Berry
EVs 252 Attack/252 Spd/4 HP
-Pursuit
-Ice Shard
-Brick Break
-Night Slash

I originally trained this one for online battles. Even though it has incredible speed this ,it has failed most of the time.
All because of paralysis cutting speed. That's why I have Ice Shard. But Ice Shard never did much damage either.
So I was thinking of changing Ice Shard to a a better Ice move and Pursuit to a better priority move.

Starmie@Expert Belt (Timid)
Ability: Natural Cure EVs 252 Sp. Attack/252 Spd/ 4 Sp. Def
-Surf
-Thunderbolt
-Ice Beam
-Hidden Power Fighting
This Starmie can take care if at least 13 of the 17 types, and expert belt backs it up.
The only problem it might have is dealing with electric types.

And finally I use this Pokemon in the battle hall:

Porygon-Z@Choice Specs (Modest)
Ability: Adaptability EVs 252 Sp. Attack/252 Spd/ 4 HP
-Tri Attack
-Hidden Power Ground
-Ice Beam
-Dark Pulse

Tri Attack hits hard. Especially with the Choice Specs. So far my Porygon-Z has always gone first to attack. Except once where this Jolteon hit me. But it's pretty durable and only did 40% damage with his STAB Thunderbolt.

What do you think of my team?
