-Castle Siege
Strike Battlefield strike Battlefield strike Battlefield.
I honestly believe that it is Greninja's overall
worst stage. The haven of platforms reduces his ability to punish landings dramatically, nerfs Usmash even more, makes it hard for
Greninja to land, and occasionally the top platform even saves enemies from Uthrow to Uair. It's a terrible,
terrible stage for Greninja.
Lylat is terrible for pretty much the same reasons only it also nerfs Shuriken with its tilting. On the other hand, Bair can put the opponent in a bad position under stage, so it's a bit more MU dependent, but if you can't think of a reason the opponent wouldn't go Lylat, then definitely consider banning it. Otherwise, ban Battlefield.
I would say that Kongo Jungle (dat barrel and huge ceiling) and Castle Siege (platforms+statues+that little hump on the third transformation) are also not preferable for Greninja, but they are more tolerable than the other two.
As for good stages, I believe that Town and City and Delfino are two of Greninja's best stages. Town and City gives Greninja a ton of room to run around, the platforms are unbelievably helpful for Uair chasing, and it has a low ceiling. Delfino has a lot of absurdly low ceilings and close side-blast zones which can make Greninja's mid-percent combos deadly (I got a dash attack to Fair kill once at around 50% on the umbrella transformation). Like Town and City, its neutral position platforms can help out with Uair chasing as well. The only things that aren't great for it are some of the awkward lay-outs (the Noki Bay entrance transformation, the one where you're on a building, the super steep slopes island, and the green platforms sticking out of the ocean) and it's smaller than Town and City.
Aside from those two, Smashville and FD are both great stages for Greninja that serve different niches. FD allows more run around room while Smashville is small enough to allow Shuriken to travel across most of the stage.
Wuhu Island and Duck Hunt are also good choices for similar reasons to FD. Wuhu Island is actually large enough to allow Greninja to stall slower characters out entirely. Duck Hunt is also a large stage, but it does have the problem of a high ceiling with close side blast zones.
Those are just my own opinions, though.
