Mud Shot / Power-Up Punch Poliwrath

If you enjoy PVP, can spare the stardust and will have chances to use it, absolutely. I would love a Mudshot/Ice Beam/Power Up Punch Poliwrath. But if you can only invest resources into Pokemon that will earn you rare candies and TMs, then don't do it.

Bring him up to 2500 and try how he performs in the middle league. That`´´´'s how I use my Mud Shot Poli.

Legacy PuP Poliwrath is good in Ultra because it can go toe to toe with Giratina and counter Giratina counters. The only time Poliwrath wont do well against Giratina is if Giratina gets an Ancient Power proc. It's worth the investment if you see a lot of Giratina. Ice Punch also lets you counter Flying types.
