So we're getting down to the wire here, and I'm going to give one more post before I start the countdown. What I'm interested in here is building a Pokemon that adds versatility to a sun core. What Pokemon can work with other Pokemon already in a Sun team and with Pokemon that might be good candidates given another Pokemon to add to that core. Here's what I'm currently thinking, and I think we've covered a lot of ground and its time for the 24 hour warning. Electric / Grass adds a Pokemon that can pivot into Water moves, threaten every kind of Water type in Rain and most Hurricane users, can hold its own against Sand and has no truly critical weaknesses. I don't consider a weakness to unSTAB Ice Beam so compelling that it negates the effectiveness Grass presents against Water and Ground, since even if it doesn't resist both (Grass/Elec forfeits the Ground resistance) it still provides the offensive presence necessary against them. Electric / Dark is a little tougher to manage down the road to make sure it isn't the latest and greatest Rain mon, but it does have serious potential as a physical attacker that has STAB on Pursuit to act as a trapper, and can be built in a way to make it very favorable to Sun. Essentially it locks onto a specific threat to sun while providing general utility against Rain without opening up an Ice weakness in exchange for a little more weakness to Ground, a threat that can be managed in several ways that include items as well as abilities. Grass / Dragon is difficult to sell on a one on one basis, however the point of this direction is we're forming a core. Grass / Dragon interacts well against Water and Ground moves, and while it does cry out for Ice Shard bait, the only common user is Mamoswine. Mamoswine and Sun share an interesting relationship, but perhaps the best thing about it is with Grass / Dragon you can add Rotom-H to your core as an Ice resist that can threaten waters with Electric STAB. It also provides a Ground immunity that can aid you in the third part of the core formation, Heatran. It's true that Rain Pokemon can hit all 3 of the Pokemon SE with Water+Ice coverage. But there are already a slew of Pokemon that resist Water/Ice, its just they all prefer Rain. The problem isn't that Sun doesn't have a viable Water/Ice resist, it has the most populous type in the game to draw on if it needed that, and there's even a few Water-types with Fire Moves (Hiya Tikibro.) In Sun the Water weak isn't even really a problem for Heatran/Rotom-H. The problem is getting Ninetales back in, and by making an Ice move prediction even a considered option for a Rain team to use in normal battle situations, you give Ninetales a chance to switch in or enable Rotom-H as an Electric pivot. Another typing I'm considering for the slate is Grass / Dark. Grass / Dark is a great typing that is held by mons I find awesome, but that just can't compete in OU. The typing just isn't that conducive to sun sweeping, as proven by Shiftry, and you really don't want to be initially slower than the premiere U-turn user in OU Cacturne. Grass / Dark fuses the purpose of Electric / Dark with the water and ground resistances that make Grass favorable, and it doesn't have any potential optics issues that an Elec / Dark with an explicitly "Grass" ability might generate. The key characteristics I find in all of these types is that a) they threaten Rain and water types as pivots or enablers of pivots b) Built properly they can have an excellent orientation towards our goal, c) they have no SR or EQ weakness, and even if they have an Ice weakness their presence means Ninetales has an attack to switch into to reset Sun and d) they bring new STABs to the table to enhance Sun's offensive presence on their own and through the cores they enable. Finally, a brief word on mono-types. While I'm not specifically excluding them, the problem is they already exist in droves, including various sun sweepers (Tangrowth) and Rain attackers (Jolteon) and as of yet none of them have been able to alter the metagame, so I feel we need a dual-type to achieve the goals of the project. EDIT: After a brief discussion I have decided to add Electric / Ice into the mix. While this is weak to SR and EQ, I feel it has enough going for it directionally that it would be worthwhile to slate. It's neutral to water and threatens it, it resists Ice so it easily takes the most common coverage move for Water-types, it has no 4x weaknesses, and given a proper niche it could combine with Venusaur's Fighting resistance and Chandelure's immunity. Ground types in OU are often critically weak to Ice and the typing also gives us a method to take down the Latis. I feel it is a decent neutral type which provides a unique balance of weaknesses, resistances, and capabilities that can be built on towards the goal of the concept. EDIT 2: Scrap Elec / Ice. Grass / Fighting is my final choice. It adds a valuable SR Resistance to a Sun team, can be tailored in a way to differentiate it from both Breloom and Virizion, we had previous established that Fighting types are not something we have a problem with conceptually, and after discussions about Elec/Fighting I just feel like if I'm going to go with Fighting it should be attached to something that naturally resists Water and Ground, because those resists are more fundamentally needed on a Sun team than other playstyles. Double Grass relieves pressure from Venusaur to be the Water attack sponge, and a 2x unSTAB Ice Beam weakness from most Rain attackers is entirely manageable - and a predicted Ice attack is just a chance to switch Ninetales back in.
