Oh lord Normal, my favourite type. Anyway, if you're going to use Staraptor, I'd recommend the following set:
Raptorflakes (Staraptor) (M) @ Leftovers Ability: Intimidate EVs: 252 HP / 172 Atk / 84 Def Adamant Nature - Brave Bird - Close Combat/U-turn - Roost - Defog
This is my main set on Staraptor in mono Normal. The HP and Def investments give you the chance to bulk most unboosted physical hits, especially when combined with Intimidate. It also hits big threats to your team, most notably Fighting types like Conkeldurr. Roost helps you to recover from the damage done to you by rocks or switching in or whatevs. Defog might not be very suitable on this team, with Smeargle's hazards. Still, it helps you to get those pesky rocks, spikes and webs out of there. For the last move, I'd prefer Close Combat, but U-turn is a possibility, since you can get a free switch-in. Both have their pros and contras, feel free to use whichever you want.
Then, Porygon2.
Derpygon2 (Porygon2) @ Eviolite Ability: Analytic/Download EVs: 252 HP / 212 Def / 44 SpD Calm Nature - Magic Coat/Toxic/Thunder Wave/Tri Attack - Recover - Thunderbolt - Ice Beam
Based god Porygon2. With this set, you have created an absolute monsters that bulks pretty much all unboosted hits, no matter if they're special or physical. I chose Analytic as the ability, because Porygon2 moves slower than most mons. Download is a possibility too, but no Trace, please no. Recover is...well, you need a Recover. That's just obligatory. I am a fan of running Tri Attack on my Porygon2, but not in mono Normal, because at least half of my team already carries Normal moves. BoltBeam gives excellent coverage. With Ice Beam, you'll be able to freeze Dragon types to death, and Landorus can't bulk it either. Thunderbolt hits creatures such as Gyarados, but it also gives neutral damage to Steel types, which are not fun to face with Normal monos. You can choose the last move. The obvious things to put there are Toxic and Thunder Wave. Status moves are always a good thing to have. You could put Tri Attack there, but I don't recommend it. Really. Then the thing I use: Magic Coat. You never see this move, therefore, no one expects it. But when you use it, you bounce back all rocks, spikes, status moves, taunts...pretty much everything Magic Bounce bounces back. But only for that turn. Nevertheless, it's fun to see how you bounce Skarmory's rocks back to their Flying mono, or cripple creatures like Mandibuzz by bouncing back their Toxic, burn Rotom-W with their own Will-O-Wisp, and render haxers like Togekiss and Jirachi useless by paralyzing them with their own Thunder Wave. Truly, I've never seen a Pokemon make so many people ragequit before.
