nah i traded that shiny one away long ago (it was a load of crap anyways). This one is timid with max speed and hp. It had two real reasons to be on my team. 1: Lay out toxic spikes, being pretty fast and all it could do it pretty quickly, and 2: Counter mence, as i didnt have a very solid mence counter in the beginning and with SR its always a OHKO. (also at worst it ties in speed with mence).
Anyways... ya i dunno if id use a mixed swords dancing tentacruel but i was considering mirror coat myself. Also kina thought about accupressure but then i cant learn rapid spin =T
I've been meaning to EV two new tentacruels for myself but haven't gotten around to breeding them and adding them to the list of 4 pokemon that need to be trained.
I'm making a mirror coat one which could come in handy since it has such great sp.def and no one expects mirror coat.
And a Tentacruel that I think is called "Druidcruel" it has SD/Waterfall/Poison Jab/Hydro Pump and it's meant to be a wall breaker. (i.e. with life orb and a SD poison jab/waterfall OHKO's standard blissey and with life orb Hydro pump OHKO's skarmory as well all in one set.)
EDIT: only one that comes to mind is stockpile maybe.
