This looks deadly indeed. I think my one question is other than stating the obvious, what was the Bulky Dancer EVs for? I know the HP made sense, but that much Special Defense? Why not invest into Defense instead? Unless I'm missing something seriously important.
To be honest, I'm not quite sure exactly what the bulky dancer EV's are for. I know a few people have said they've liked the Bulky Dancer though, so I wanted to keep the EV's somewhere.
This opening line is odd-sounding now that the Bulky Dancer set is removed. Probably should omit this line.
Good point, I'll change that.
This is minor and will rarely happen, but as a sweeper, Lucario would benefit more from the potential Speed boost that Steadfast gives than just avoiding flinches altogether, since Lucario will basically outspeed any flincher after the boost.
Well...one instance where that wouldn't work is against Yanmega (speed boost, you won't outspeed him so getting off one free hit is more valuable). It's also less useful against flinch-hax Togekiss, since if you're paralyzed speed boosts are obviously useless. Steadfast would be better in most other situations (like against a Gyarados w/ Waterfall), but I can't think of many other pokemon that rely on Flinch offhand. Overall, it might just be better to not suggest abilities, as both have advantages and disadvantages. Maybe I should add that to other options, too...
