I also have one more question this exact team for some reason does not allow me to fight in random matches, does anyone know why?



Thanks for the help guys!

You don't have to post the stats itself; you just have to post the EVs.

For Cofagrigus, I'd try this:
-Calm Mind
-Shadow Ball
-Hidden Power (Fighting)/Will-o-Wisp
-Rest/Will-o-Wisp
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers

I can see where you're going with Swagger + Foul Play, but Foul Play itself is a pretty unreliable attack:
-Earthquake
-Crunch
-Outrage
-*insert filler move here*
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Choice Scarf
Ability: Moxie

EVs for Reuniclus are 252 HP/252 Def/4 SAtk

Klinklang's movepool is insanely shallow anyway, so this might be of better use:
-Shift Gear
-Gear Grind
-Return
-Volt Switch
Nature: Adamant
EVs: 124 HP/252 Atk/132 Spe
Item: Leftovers/Life Orb

Try this Galvantula; it could use some more type coverage:
-Bug Buzz
-Thunder
-Energy Ball
-Hidden Power (Ice)/Volt Switch
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
item: Life Orb
Ability: CompoundEyes

Also for your question, I don't really know.

Thanks for the input i like that gavantula, and the reason i posted the stats and not the evs and for the question i asked to show that they were not over ev'd or hacked in anyway but again thanks for the input.
