Shedinja can't have both Baton Pass and Swords Dance on the same set, since they're both Ninjask-only moves learned at different levels. You can get either Baton Pass or Swords Dance by evolving a Nincada at the right level (45 and 25, respectively, as Kiyo said).
Yeah that's a pretty decent core as they all pair well offensively and they shouldn't be too hard to build around, another option for a Psychic/Dark/Fighting core is Gurdurr, Musharna, and Skuntank if you want to go for a bulkier build.
yes it will still be poisoned and take poison damage, the same is true for both fire and electric types.
Types will not undo the effects of status; however, gaining / regaining an ability that specifically prevents said status, namely Magma Armor, Water Veil, Immunity, Insomnia, and Limber (but not Leaf Guard for whatever reason) will erase the respective status ailment immeditately.
it runs fire blast and grass knot to lure different things, i.e. rhydon, ferroseed, mawile, etc.
No it is not viable, Zangoose has Close Combat coverage that at least let's it threaten normal checks whereas Watchog has nothing of this kind and is walled hard by rock and steel types (iirc). This is among other reasons such as Zangoose's power
i'd reccomend adding a fire water and normal resist somewhere, solid options that fit well on voltturn include lanturn, dd rhydon, magmortar, and pyroar although you can go with pretty much any voltturner or offensive threat that fills tht role
I've built a team with Coil Arbok, and one option I really loved to use deal with Arbok counters and checks is boom Shiftry. Things that can deal with the purple snake (talking about the EQ/Coil/Sucker Punch/Gunk Shot set) includes: Psychics, bulky Grounds (quaggy included), bulky Poisons, Ferroseed, Archeops and TWave EQ Regirock. Leaf Storm kills Rocks and Grounds, Knock Off heavily dents Psychics and Ferroseed, while Knock Off + boom + SR is enough to kill any bulky Poison. Unfortunately he can't really do much against Archeops apart from maybe putting him in Defeatist range so you can play 50/50 with Arbok about either Sucker Punching or EQing. Ofc, there are a lot of other options that you can work with like Fire Blast+HP Grass Skuntank, offensive Poliwrath... I'm just talking about one specific set I've had some success when using with Arbok n_n
Using the Rest set, so no Sucker for me.
It's Explosion.
