What do you need this for?

Answer 1

I would say if you want to go the defensive way I would use Porygon-2 with Eviolite:

Porygon2 @ Eviolite
Trait: Download / Analytic
EVs: 252 HP / 4 Def / 252 SpA
~ Tri Attack
~ Ice Beam
~ Discharge / Thunderbolt
~ Recover

Porygon 2 Smogon

If you want some raw power I would run Porygon- Z

Porygon-Z @ Life Orb/Choice Specs / Choice Scarf
Trait: Download / Adaptability
Modest Nature
96 HP / 252 SpA / 160 Spe
~ Tri Attack / Hyper Beam
~ Ice Beam
~ Thunderbolt
~ Recover/ Dark Pulse / Psychic

Porygon Z Smogon

Answer 2

I think you should keep it as Porygon2 with the Eviolite - it has better stats overall, and with the Eviolite it overpowers PorygonZ.
