#FreeWobbuffet
Before I start, I'd like to apologise for bending the rules a little by including a slash on Stunfisk's set. The reasoning for this is because they are both equally valuable assets for the core, so the one which is used is very much dependent on the makeup of the remaining three team members.
This is a revamped version of a core that I originally showcased in one of my RMTs back before the days of Wobbuffet's
persecution ban. It is an offensive darkspam core featuring Stunfisk to fill multiple roles on the team. Things that your average darkspam team needs to cover includes VoltTurn, fast electrics, Thunder Wave and birds. In addition, filling the role of Stealth Rock user is an absolute must for such teams maximise the rate at which they can wear down each other's checks, and having something which can provide support by being on the field alone is extremely welcome to such teams. On most teams Helmet Lando-T or FatChomp will suffice to fill this role, but on frailer builds I have had success with this badboy due to a number of shortcomings that that twosome faces with regards to the role.
Firstly, Stunfisk is capable of acting as a guaranteed switch-in v.s. electrics due to the big three failing to 2HKO it with HP Ice before a boost and it taking a measly 40 BP hit from Grass Knot, making it an even weaker hit v.s. it than HP Ice. In addition to this, its access to Static allows for it to provide lots of passive support when used in conjunction with Rocky Helmet, being capable of very easily crippling physical attackers like Talonflame, Bisharp and Mega Pinsir which it commonly switches in on. Its access to STAB Discharge allows it to spread paralysis quickly without sacrificing the ability to combat Talonflame and Mega Pinsir consistently, and its capable of pressuring MMan and Raikou with its ground STAB. It's access to Pain Split also sets it apart because it allows it to take advantage of things which try to use it for a free switch-in (namely electric immunities, although resistances are also problematic - albeit pressured by Discharge's high paralysis rate and Static only adding to the pressure in the case of contact users) to heal and to put a dent into them, making it easier for them to be overwhelmed by its teammates. Yawn is also of note for its ability to help Stunfisk retain momentum v.s. stuff that tries to come in on it - namely Lati@s (helps you retain rocks and stops them using you for a free switch-in), Landorus (forces it to U-turn/switch out while providing a buffer against EQ, allowing Weavile to come in for free and guarantee a Swords Dance) and other miscellanious Defog/Rapid Spin users - and provide lots of support to Stunfisk's teammates - allowing for easy set-up.
Credit to
-Magic- for the EV spread. It is better suited to the current metagame than the one that I had been using up until recently was due to the decline in AV Raikou usage making modest+152 offensive investment unnecessary for the most part. It hits 370 HP and the final defense jump point while maximising Stunfisk's SpD stat with what is left, allowing for very solid overall bulk and making it more consistent at being able to blanket check stuff repeatedly. I believe I have already covered the purpose of the moves, but Rocky Helmet and Static are musts due to the sheer amount of passive support that they bring to the table.
Now onto the sets of the darkspam core. Bisharp is a mixed variant with Grass Knot to lure and eliminate Quagsire consistently, which is otherwise a big headache for the core to face, and I have opted for Lonely because +Spe Bisharp is too weak for my tastes. The reasoning behind going -Def>-SpD is because there is actually a hit that it needs the extra points in SpD to take. I can't remember what it was but ages ago someone calced a load of shit and it needed it for the hit. As for Weavile, I opted for SD because it is a completely monstrous set which also takes advantage of the momentum that Yawn brings to the table to get free setup turns.
Mwahaha! I beat -Magic- to a Stunfisk core.
