Yare yare...
I am so disappointed how you guys are bitching about another competitive pokemon.
Doesnt it remind you a bit of aegislash? ^^ Changing Type / Changing Form? No? well maybe its just me^^
ANYWAYS lets get to the real shit.
Does Greninja need to go to uber?
My answer is no.
Upsides to Greninja:
-THE POTENTIAL for excellent STAB coverage (which you all should have noticed by now)
-There is no counter to this pokemon
-Ways of countering enemy moves by changing type (which is very risky tho)
Downsides to Greninja:
-Can switch in as bad as the enemy can switch out IF NOT EVEN WORSE
-Loses to choice scarfed pokemon
-Loses to neutral priority after LO and SR in OU
-Gets worn down quickly (no recovery, life orb recoil, SR are neutral)
-Can not run : Ice Beam, Hydro Pump, Gunk Shot, Grass Knot, Low Kick, Extrasensory, Dark Pulse, Hidden Power Fire, Shadow Sneak, Spikes, U-turn, Rock Slide;
WHAT DO YOU NEED TO TO BEAT GRENINJA?
Lets assume you have Stealth Rocks up wich you usually have.
Some examples of what I figured out I could do on a team I did not even THINK OF GRENINJA in my teambuilding:
-Switch in Choice Scarf Keldeo into a predicted ice beam / hydro pump / gunk shot / low kick / shadow sneak / spikes / hidden power whatever.. LET IT TAKE LO DAMAGE and klick hydro. GG
-Switch in Life Orb Bisharp into a predicted ice beam / gunk shot / ... LET IT TAKE LO DAMAGE and klick sucker punch. GG
HOW DO YOU GET TO KNOW WHAT MOVESET GRENINJA IS RUNNING?
Scouting.
Since only Ice Beam and Gunk Shot are on every Greninja and if the enemy Greninja is running extrasensory HE DOES NOT EXPECT YOU TO KNOW THAT!!!
So if you have the matchup KELDEO VS GRENINJA there are 2 things he can do:
1. Klick Extrasensory (if you are scarfed you could just klick secret sword...) = He has Extrasensory ->>> you need to scout for 1 more move
2. Switch out = He has no Extrasensory ->>> your keldeo will fuck his greninja
There is no way he will go for ice beam / w.e. since extrasensory is not that common on ninja and he will try to kill you with this surprise factor.
SO NOW YOU CAN EASY SWITCH IN SOMETHING IMMUNE OR RESISTANT TO PSYCHIC AND SCOUT FOR EXTRASENSORY!
As addition if you are bisharp you can klick sucker punch now and either force it out which will force it to switch in again and greninja hates switching in or will kill it.
You could also go for sword dance if you think he predicts you to sucker punch and sweep from there ^^
That all being said I think Greninja is a very good mon in OU and can beat inexperienced people by itself however if you get higher on the ladder you can play around it and it does not deserve a bann.
ok fuck eye cancer pls
on a serious note you forget one thing: greninja user can switch out, because Keldeo and bisharp can't trap greninja: nothing is stopping greninja from switching out to a keldeo/bisharp counter (and in the case of bisharp, it gets a free switch because sucker punch does shit, gg)
also this does not take into account that the 'scouting' is not something that can be done at zero cost, and often the cost of scouting is too much for balanced teams to handle because greninja literally can 2hko the entire tier with stealth rocks up except for chansey and porygon2.
playing around it isn't even that easy, considering that not every offense team is capable of running chansey (correction, i mean, all of them). choice scarf isnt even that hard to deduce lmao
EDIT: I also have a question for you. What do you do when you see a charizard? Tell me one mon that can switch in and beat him 1v1 but I will be able to chose what kind of charizard it is since people always do that with greninja too and you have to scout for charizard sets as well.
