I haven't read the entire 53 pages of this, but I have a Physical build that I find rather entertaining. I am also looking for any feedback on it.

Set Description:
The set utilizes predictions, speed and raw power to overcome some of Greninja's current counters. As a summary, most people switch unprofitably for them. Most people bring in Special Sweepers / Walls against him and just fall to a 110 STAB Acrobatics (some in two hits, but you're faster). This does an incredible amount of damage against Mega Venasaur which is popular in my meta. Once they are stable, you utilize a combination of your own moves to dodge opposing moves while dealing damage. Each move grants Greninja an immunity to at least one type, this is where predictions are key.
This makes short work of Lucario and Breloom. Shadow Sneak first, then Acrobatics; if they use Mach Punch they miss both times.
This can set up against most electric types by using spikes and protect.
Fire, Rock, and Ground have difficulty hitting him as long as you can predict better than your opponent.
Biggest counters to him are Rock or Steel physical walls. While they more-than-likely can't hit you, they can setup against you.
Prankster / Gale Wings will make short work of this Greninja as it needs all the power and speed it can.
This Greninja is definitely a glass cannon; use with care.
Other options:
You can hold a lum berry if you plan on not using him as your lead and switching in on a status. That works less for me than holding nothing.
You can swap Protect for another move, I have tried Toxic and U-Turn myself (U-Turn is better). You could also use Rock Slide, I have it on my Triple Battles Greninja, but I haven't tried it with this one.
You can give it a Jolly nature, I recently got one that is Jolly and am indifferent. I haven't had a battle where that's mattered yet.
Personally, I have been using this for the last few months, and I am in love with it. I finally have a video of me using it yesterday. It had some help, but you can see how much work he puts into the team...
