Yoooo, guys! Why don't I see any mention of a lead set for this guy?
Greninja@ Focus Sash
Ability: Protean
EVs: 4 Atk / 252 SpA / 252 Spe
Hasty Nature
- Scald/Hydro Pump
- Taunt
- Spikes/Toxic Spikes
- U-turn
Spikes are most certainly not dead this gen. You've just got to be more careful with them, is all.
You use this by leading with Greninja and setting up spikes of your choice. Your Taunt is faster than all but the rare Aerodactyl's Defog, and he won't exactly enjoy taking one of your water attacks. If a different Defogger decides to rear its ugly head, Taunt the bloody thing, then U-Turn into something that can handle it better - for example, Tyranitar into Latios. Even if you mispredict, due to the Focus Sash, you live to fight another day. Scald and Hydro Pump are for slightly different purposes; one is for crippling switch-ins with the burn {mostly for passive damage}, whereas the other is for a craptonne of massive damage right off the bat, able to 2HKO Skarmory so it can't even think of Defogging or Brave Birding you, and always OHKOing Excadrill, for example. Of course, given the nature of Protean, you can slap virtually any move on there for something your team has trouble with, as Greninja's hardly weak sauce. Espeon, Xatu, and Latios can't switch in to Dark Pulse, as well as the obvious Starmie, and it's possible [albeit unlikely] to 2HKO Exca with that. I could also see someone forgoing U-Turn and putting both Dark Pulse and [insert water move here] and going Timid, but imo the coolest thing about this set is that it "flows" nicely and can pop into something else seamlessly, and it works nicely for Voltturn, as they like to force switches, to gain ground in a way that is somewhat similar to stall. Your mileage may vary, though.
