I do think Wartortle has a place on stall as an incredibly reliable Metang check. On non-stall, he tends to be too passive, and gets outclassed by other waters (as you said). I think that your move set is perfect for accomplishing what Wartortle wants to, I use the same set (though I have been running max defense bold). Rest is great with Aromatherapy support, which is essential to fit on stall. I've never built a stall team using Shedinja, but I'm sure his anti-rain properties make him usable with support. Most rain sweepers (and water types in general) run water STAB, Ice Beam, HP Electric or Grass, and Rain Dance or some other filler. Shedinja entirely walls those moves. But, a stall team can also run more reliable rain checks like a fat SpDef Lickitung, Roselia, Bellossom, or their own SpDef water type.
I'd like to talk about Shedinja some more. Going off of his ability to wall offensive variants of every water type Pokemon in the tier, maybe he can be an effective hit-and-run pokemon. Practically every other Wailord check is a bulky grass or water that attacks from the special side. Physical offense teams don't have a fun time switching into Wailord. Maybe Shedinja can provide valuable defensive utility while still hitting like a truck.

Shedinja @ Choice Band
Ability: Wonder Guard
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Shadow Ball
- Silver Wind
- Hidden Power [Ground]
- Baton Pass
Baton Pass is nice paired with Diglett in particular because Shedinja draws in fire and rock types. Physical offense teams don't give Roselia or Cacturne much room to breathe, and they can slot Hitmonchan fairly easily, so I do not think spikes inhibit Shedinja much here. Toxic variants of water types would give the set trouble, so Shedinja shouldn't be the team's only water check.
What are your thoughts?
