I found a couple of
useful links if you haven't seen them already.
I kind of agree with Gamer though, I don't see the harm in giving it Stealth Rock. Spikes and Toxic Spikes are certainly a no-go, but this is a supporting Pokemon, so Stealth Rock is a nice touch.
I don't want Will-O-Wisp because that limits what can come in on its STABs. Gyarados and Salamence will both be discouraged from coming in, and things like offensive Suicune and even Vaporeon don't like losing their Leftovers recovery (and actually taking damage each turn). And not all Fire-types get Will-O-Wisp, just look at Blaziken, Magcargo, Camerupt, etc. A lot of Pokemon that have Will-O-Wisp used to not have it, like Moltres and Entei. I see no reason to give it such a deadly option. I guess I'm not completely against something like Lava Plume though since the power drop makes up for the burn.
As for recover, I don't see the problem with giving it Recover. Its stats aren't really great for an attacking set (though they're certainly not bad), and it's walled by enough that even if you choose to go that route, it won't be superior to the spinner in most cases. We can always lower its stats in the editing process if we have to.
Explosion is interesting...I don't really see the harm since it's just so weak, but on the other hand, that's just encouraging an offensive use of the Fakemon (probably a Fire Blast/Earth Power/thirdmoveforcoverage/Explosion@Life Orb type of set), so I don't know if it's a good idea.
I think Knock Off would be an interesting addition. I remember back in the DP days when Tangrowth could pull its weight just by knocking off Salamence's Choice Specs or Life Orb. I think it's something to consider just as an interesting little side option of sorts.
I think we should give this Refresh because of Toxic Spikes, which will poison this before it spins stuff away (and Rotom could theoretically try to stall it out by doing that). Given the fact that it will probably have moveslot syndrome anyway, this seems like a harmless addition to me.
Also, I forgot to include priority...will this have any priority moves? I don't really see too much harm, as it could even make it a decent lead in the Starmie tradition (aka it would spin rocks away)...though it probably doesn't need priority to do that. I don't see the point in adding that.
Just some thoughts etc.
