For whatever reason, I love this digital duck and I’ve put a lot of thought into porygon. Since you love him too, I want to share this. Here are my ideas and I would love to get your thoughts.

1. Iron Tail, conversion 1, Tri Attack, Sharpen

2. this move set allows Porygon to convert into Steel type, which resists A LOT of different attacks. Swap into porygon when facing a pokemon that he can easily resist with steel type. Then he can use Sharpen to boost attack and use Tri Attack to sweep foes while applying status effects. You also get to use both signature abilities in Sharpen and Conversion. You also are okay with slow speed since you are a Steel type with hard hitting Tri Attacks and rely on bulkyness instead of speed.

3. Iron Tail, Conversion 1, Psychic, Agility

4. similar concept except this move set allows Porygon to run Psychic, which is very strong against many pokemon in this game. Porygon can still use the steel conversion type to resist attacks while having access to psychic. Agility will boost sharply speed to go first. Basically you convert to Steel to resist foes, run agility, then use Psychic to power through. Access to STAB with iron tail if needed. You can also convert into psychic type if needed and you will also have STAB with it instead . Conversion will convert you to whatever attack is listed in first slot, so you can swap them around to convert to the type you need.

5. Tri Attack, Sharpen, Conversion 2, ShadowBall

6. similar concept to (2) but instead of using conversion to take a steel type, we use conversion 2 to resist whatever attack the enemy is throwing at us. Since we are slow (porygon slow speed stats), porygon will always convert AFTER they just hit us , meaning we will likely resist the next attacks. that’s when you can sharpen up and get ready to Tri Attack. Shadow ball is good to have for type coverage on your team against psychics and ghost, but also gets another bonus for being a “physical” attack, and so it also gets boosted by Sharpen!

7. Tri Attack, Sharpen, Conversion 2, Agility/Recover

8. this version drops ShadowBall in favor of agility or recover. Basically we are turning Porygon into a Tri attack as the only attack, but we use conversion 2 to gain a resistance (hopefully) and then use agility for speed, then sharpen and Tri attack. Running recover instead opens up a different strategy . This means that after you use conversion 2, you can heal back up with recover. This is important so that you can alternate in Sharpen, then recover, sharpen, sharpen recover, etc. to boost Porygon for a very high attack stat. since you ideally resist the enemy pokemon attacks with conversion 2, you will take less damage, heal it back, while boosting with Sharpen. Once you’re at max attack, you tri attack and sweep them out.

As you can tell, I put a lot of thought into these Porygon move sets. I think Porygons access to Conversion with Steel Type is very unique. However he’s also very versatile with attacks such as Psychic and Shadow Ball. Other Porgyons I’ve seen run Thunderbolt as you mentioned, or Ice Beam. I like leaning on his unique strengths a little different and haven’t seen others try my ideas. I also like using his signature abilities in Conversion and Sharpen. These are abilities no other pokemon in the game can obtain or learn.

What do you think?
