<p>In Platinum, Porygon-Z has had to adapt its strategy a bit. Using Nasty Plot, it packs fearsome power, but is open to revenge kills from Scarfed Heatran, Shaymin-S, and Scizor. This set attempts to remedy these issues by using Substitute to block revenge killing attempts, and a Salac Berry to ensure that you outrun most enemy Pokemon.</p>
<p>Porygon-Z is a fearsome special attacker, and as such, encourages switches to dedicated special walls. Using this free turn, you have two options. If your opponent has a Blissey, you should Nasty Plot first. This will lead your opponent to believe it is a regular Nasty Plotter, and they will likely attempt to Thunder Wave you. This will allow you to set up a Substitute on them. You can Nasty Plot a second time as they break your Substitute. After two Nasty Plots, you should be able to 2HKO most Blissey. Most opponents will not Thunder Wave again, thinking you will Substitute. If you Nasty Plot, then Substitute, then Nasty Plot, then Tri Attack, then Substitute, you will beat every Blissey with a Salac Boost. If you play intelligently, you may even walk away with a Substitute depending on their reaction to your first Tri Attack. Flamethrower/Toxic Blissey has no chance. With the given Special Defense EVs it will take two hits to break one of Porygon-Z's Substitutes with Blissey's Special Attack of choice (Thunderbolt, Flamethrower, or Ice Beam). Take advantage of this, and you should very easily win the game.</p>
<p> Against a more offensive opponent, you should Substitute first. When they send in a faster Pokemon, you can Substitute as they break your previous Substitute. Repeat once more, and you will be at one-fourth of your HP, and have a Salac boost. You will more than likely outrun them, so you can either Nasty Plot, or kill them off, leaving you with +1 Speed and +2 Special Attack, or +1 Speed and a Substitute. Since Scizor is very popular, you should strongly consider keeping your Substitute instead of going for the Nasty Plot. Its Bullet Punch will force you to switch or die if Porygon-Z is caught exposed. Even with only 370 Special Attack, Porygon-Z can do considerable damage to the opponent, and makes a good cleaner.</p>
<p> It is difficult to get good type coverage with only two moves. This problem is compounded when your STAB is a Normal type move. However, Tri Attack and Hidden Power Water, while a strange combination, is only walled by Empoleon and Shedinja, who are very rare. Hidden Power Water deals massive damage to Tyranitar, Heatran, and can even OHKO Gengar after a boost with some prior damage. Another Hidden Power that preys on a weakness that both Tyranitar and Heatran share is Ground. It also hits Jirachi and Metagross, but this leaves you a sitting duck against Gengar and Rotom. This is not a recommended option, but viable nonetheless. Tri Attack and Dark Pulse work as well, especially if you fear bulky Ghosts like the new Rotom Appliances ruining your sweep. Being walled by Tyranitar and Heatran isn't a very good idea, as they are very common, so it is strongly recommended that Hidden Power Water be your choice. However, your attack selection should be dependent on team combinations. </p>
