Guide
Important: Do not fight for the jungle, If jungle is already taken, you can actually use any lane, but avoid entering in fights with crowds of enemies unless you have support of your team mates or until you become Greninja and you are sure you can beat them.
This Greninja focuses on maximizing damage, but it's very glassy, so be sure you don't get in a big fight alone.
Your goal in top and bottom lanes would be to keep pressure and sneak some goals using smoke screen when there are no enemies around. If you have a good team mate supporting you, use X-Attack to do heavy damage to your low-level enemies. This will help you being able to level up without being bullied at the beginning of the match. You need to reach level 5 ASAP.
Jungling strategy:
When you start, go immediately to the middle with a Substitute, so you will jump the wall and can start attacking Lillipup immediately.
While you are in the middle lane, keep using Substitute to go faster from top to down, until you learn Smokescreen.
After you clear your side of the Jungle, try to score in the top or bottom lane, using the trampolines and then hiding with Smokescreen. The enemies won't expect that and you can even surprise them later from the back (using X-Attack), while your mates attack from the front.
Help your mates if they need help or go back to the jungle. You won't be much useful until you learn Water Shuriken, so focus on level up so you can help better your mates.
Later, it's preferable that you go first to the Drednaw.
X Attack + Water Shuriken + Scope Lens combo is a kill machine, and you don't really need Eject Button when you have Smokescreen.
Save your X Attack + UNITE move in the last minute to do the final strike and win the Zapdos, or to heavily damage a horde of enemies that come for the Zapdos.
Be careful with strong builds of Talonflame and other speedsters because they can easily kill this Greninja. Be also careful with stunner Gardevoir and some Cinderace.
You can replace X-Attack with Full Heal to avoid status conditions (be specially careful with Gengar poison+hex and falling asleep).
