Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
There's absolutely no need to have the Substitute sets you have listed in your OP. They're basically the same exact thing as the Nasty Plot / Claw Sharpen sets, respectively, making them superfluous. By making separate sets for them, the analysis will look messy, which certainly isn't good. Just mention Substitute as an option in Optional Changes, IMO. Additionally, mention the possibility of Gluttony in conjunction with boosting berries in Optional Changes as well.
On the 'Nasty Plot' set, you have too many slashes listed in the fourth slot. Relegate Hidden Power Electric to Additional Comments to make the set look more succinct. Focus Blast / Grass Knot, in my opinion, are more useful than HP Electric. Grass Knot strikes all Water-types, including Swampert and other not-so-common 'mons like Quagsire, super effectively, while still being able to put a dent in Burungeru just like HP Electric. HP Electric does have the benefit of hitting Gyarados and some other Water-types like Vaporeon harder, but overall, I'd say Grass Knot should take precedence over HP Electric because of the aforementioned.
Focus Blast should also be the first option listed in the fourth slot because it allows this little monkey to fight back against Natorrie. Taunt should be mentioned in Additional Comments. It's useful for stopping Blissey from poisoning or paralyzing you with Toxic or Thunder Wave, respectively.
Expert Belt should be moved to Additional Comments with Life Orb being the main option since it increases Hiyakki's damage output, allowing it to break through things more effectively. You can mention Leftovers in Additional Comments and talk about the possibility of taking some EVs out of Special Attack and putting them in HP for a bulkier approach.
Now, onto the 'Choice' set: it needs an Additional Comments section. Make sure to add it when you get a chance. Remove Blizzard as a slash. Its accuracy is horrible, making it a bad move to be locked into. Ice Beam is sufficient enough for an Ice move. You should also probably talk about the differences between Timid and Modest to help the reader decide which to run. Does the loss in power given from Timid matter? What threats are faster than me if I run Modest? etc, you know what to do here.
Well, that's all. The last thing I'll do is fix your format for the above sets to make it conform to standards. At the end of the day, your sets should look like the following if you implement our suggestions:
Again, my approval is pending on these changes as well. Make sure you revise all the information in the above post before implementing it in your OP, that way you won't miss any important detail while editing.
