>>16587808This one actually does though. Talonfag, that is. You'd be an absolute retard to keep physical Greninja in on Gliscor.
Greninja @ Assault Vest
Jolly / Protean
252 Atk / 96 Def / 160 Spe
Power-Up Punch
Water Shuriken
U-Turn
Night Slash/Shadow Sneak/other coverage attack
The spread allows it to outrun max Speed Adamant bird (+Speed wrecks you regardless, but who the fuck runs +Speed) and possibly OHKO. You wouldn't send this out to eat a hit though, you want to bait the bird out with a PuP on something else. That nets you a free +1.
+1 252 Atk Greninja Water Shuriken vs. 0 HP / 0 Def Talonflame: 80-96 (26.9 - 32.3%) -- guaranteed 4HKO
>b-but muh priority courage avianThat's what the Def EVs are for you dingleberry
252+ Atk Life Orb Talonflame Brave Bird vs. 0 HP / 96 Def Greninja: 250-294 (87.7 - 103.1%) -- 25% chance to OHKO
Not failproof, sure, but it gives you a fighting chance. Even if you land 2 hits of Water Shuriken each time, that still adds to 4 hits. Also, birds without Life Orb fail to OHKO altogether so you'll be hanging on at around 30% left afterwards.
Surprisingly, Assault Vest actually allows it to balk some special hits too. Assuming a neutral hit on not-Dark frog:
252+ SpA Gengar Shadow Ball vs. 0 HP / 0 SpD Assault Vest Greninja: 127-151 (44.5 - 52.9%) -- 23.8% chance to 2HKO
And when you're at +1 you can do neat shit like
+1 252 Atk Protean Greninja Shadow Sneak vs. 0 HP / 0 Def Gengar: 240-284 (91.9 - 108.8%) -- 50% chance to OHKO
