Garchomp = Physical Sweeper
Alakazam = Special Sweeper
Machamp = Physical Sweeper / Maybe tank, but not really
Startaptor = Physical Sweeper
Luxray = Physical Sweeper
Pattern?
If someone takes out alakazam, any physical wall could kill you.
And, its good to have variety.
Now I must say, I love Swampert ( The pokemon, not the user who just answered )
But that would just be throwing more physical into the loop.
A special wall who can take hits and deliver damage would be nice, but slowking wouldn't cut it, because you would have two psychics.
I strongly suggest Milotic.
Milotic:@Leftovers
Aqua Ring / Toxic ( Restore your own health or take your opponents )
Surf ( STAB )
Ice Beam ( Coverage )
Confuse Ray ( Stalling out leftovers, and actually dealing minor damage, while not taking it yourself )
Nature : Modest
EV's 252 Sp ATK 160 Sp DEF 96 HP
So overall...
Milotic (M) @ Leftovers
Trait: Marvel Scale
EVs: 96 HP / 160 SAtk / 252 SDef
Modest Nature (+SAtk, -Atk)
- Surf
- Confuse Ray
- Ice Beam
- Toxic / Aqua Ring
Don't like my set?
Not everyone always agrees.

You can see what floats you boat.
