Dear Pokemon world,

As many of you will know, the Pokemon company is holding the Kanto/Alola singles battles competition in a few weeks and i have but one question to ask.
"What pokemon(s) would most benefit my Machamp in the singles competition?"

So heres my Machamp's info

Gen 1 Machamp.
Ability: No Guard
Nature: Jolly
Item: Choice Scarf
Moves: Fissure, Cross Chop, Thunder Punch, Ice Punch
Iv's: 31 across all stats (mostly natural but some hyper trained)
Ev's: 250Speed, 250Defense, 10Attack

My main reasoning behind this pokemon was to get it as fast a possible and due to the No Guard ability, allow it to hit with a 100 accuracy with Fissure, with all else failing then i have the defence to fall back upon.

One other Pokemon that i do quite like teaming it up with is my Tentacruel.

Gen 6 Tentacruel
Ability: Liquid Ooze
Nature: Sassy
Item: Black Sludge
Moves: Sludge Wave, Barrier, Scald, Toxic Spikes
Iv's: 31 across all stats
Ev's: 252Sp.Defense, 126Speed. 126Sp.Attack, 6Attack (these 6points can be altered)

so these are my two main focal points to the team, any suggestions would be greatly appreciated and welcomed.

many thanks
