porii sames, that reflect type starmie is BALLSY. as for tentacruel, one of the best spinner cruel sets i have seen, albeit much more aggressive than the sub toxic variants, is one that alphatron posted somewhere. it was actually an acid spray cruel. the EVs i forget, but the moveset was rapid spin / acid spray / hydro pump / ice beam or giga drain. the choice between ice beam and giga drain is basically between beating dragons and bulky grasses, or bulky waters.
i think it's often worth it right now to let go of cruel's usual tspike slot to get a lot more moveslot room in there. subtoxic is a defensive way to make use of that slot, but acid spray sets can be a great way to use it offensively. even with minimal or no investment, an acid spray on the switch can make a lot of things suffer, especially if your hydro pump is backed by rain (although cruel already lures in steel types because of its tendency to abuse toxic, and running a poison-type attack does NOT help in the slightest). iirc alphatron's original spread could 2hko a keldeo with giga drain after spraying on the switch, taking into account that the keldeo might use CM along the way. normally keldeo would just start boosting up so you'd lose unless you were carrying toxic (even then you might be facing subcm), but with acid spray you can wipe those spdef boosts away faster than keldeo can accumulate them and swiftly force it out.
anyway i managed to find the original set here
http://www.pokemonelite2000.com/forum/showthread.php?t=112026 it's quite cool if you're looking for an offensive cruel without having to go all-out on the EVs and throw away cruel's bulk, since acid spray really lets you hurt things and wards off any offensive mons who think they can use you as setup bait.
