>ITT: Spoonfeed OP V2

Hello /vp/, I need your help. I found out there's a X/Y tournament close to my place this weekend and I NEED to win this for good reasons. The thing is, I've never had a pokemon match. I'm a fast learner and I really need to get first place, but I need your experience guys. Lend me your strenght, /vp/.

>"But OP, you won't win a tournament in your first try with no experience"
That's ok, I know the odds are against me, but I have to try, and if I'm going to try, I might as well try my best to win.

>"Wow, did you tell your crush you were a Pokemon Master or something?"
>Kind of, but no. My cousin loves Pokemon, he really wants Y, but I can't afford buying it yet. I might be able to do so later if I keep saving up, but his birthday is next week and the prize for this tournament is a copy of the game. The copy I'm playing on was borrowed from a friend who's not taking part on the tournament. I must try, guys. I must win.

The rules are:
-Doubles
-Teams of 4 Pokes. (Can make various teams)
-No Sleep Clause.
-Evasion buffs/Accuracy debuffs Banned.
-Mewtwo/Yveltal/Xerneas/Zygarde Banned.
-Parental Bond, Speed Boost Banned.

I've only got one team right now:
Greninja with Surf
+
Slurpuff with Luminous Moss.
(anon named them Jiraiya and Cloudn'Cotton

Slowbro with Earthquake and Light Screen
+
Gengar with Levitate.
(still unnamed)

Help me on my quest /vp/, tell me more great synergetic duos, strategies and doubles videos.
