Greninja being banned is ridiculous. Its frailties make it easy to beat and can be abused easily upon using Scarfed or faster Pokemon. Given it is quite fast, Greninja still falls short of expectations against said variants of Pokemon.
On a similar, I had yet another exciting battle
again this morning using my new team. I'm never on PS too often, but when I am, I'm mainly testing teams on my secondary account, so if you don't see me online there, that'd be why. My team is basically solid, so I want to try and bring up an issue when using Volcarona. Volcarona's bulky set, from the battles I've been in, is very unpredictably effective. Noone really expects to see a Volc running WoW, however Heatran are everywhere.....literally... Cutting down physical attackers is easy, however Heatran makes its very presence difficult. This brings me to the abundance of Talonflame, who I've seen more often than Greninja. Maybe it's just my preference, but banning a Pokemon based on annoyance and personal dislike is uncanny, seeing as how Heatran and Talonflame are also everywhere and very much annoying. Greninja doesn't deserve a bann as much as Talonflame, imo. Or at least a bann for Gale Wings.
I also second Starmie as your best option. Starmie or Tentacruel, tbh. SubSpikes is a monster.
