Tiering Lead
I am going to start off by saying that Gallade is not broken, and really should not be banned. While yes, it might have "so many moves to choose from", only a few of them are really viable (Close Combat, Knock Off, Zen Headbutt, Swords Dance, Bulk Up, Drain Punch). I am first going to focus on the Swords Dance set, which people claim is the most broken and the reason it is so good. While yes, the Swords Dance set can break apart slower teams when it gets to switch in, but just being able to break apart slow teams does not make something broken. If you want an example of this, look at Magmortar, which has the coverage to break apart any defensive team, due to the lack of switch ins. With Fire Blast, Thunderbolt, HP Grass, Focus Blast, Earthquake, Psychic, and Mach Punch (fuck Sneasel), Magmortar overwhelms teams once it is able to get in off a slow pivot or once a mon faints. Does that fact that Magmortar is tough to handle for slow and bulky mean that it is broken? No. Similarly Gallade isn't broken because there are "no counters on Stall or Balance".
The choiced sets are also not a good reason on why Gallade should be banned, as these are 100% outclassed by mons like Sawk. While yes, having a Psychic STAB is nice, it really doesn't help it out due to the fact it brings a Dark Neutrality instead of a resistance (which is a big thing with Sneasel being so broken). In a situation where Gallade locks itself into said Psychic STAB, it is easily pursuit trapped by Sneasel (252 Atk Choice Band Sneasel Pursuit vs. 0 HP / 0 Def Gallade: 225-265 (81.2 - 95.6%) -- guaranteed 2HKO), which either kills you after a bit of chip damage or brings you down to the point where you can no longer switch it in. Gallade overall has one decent set that is not outclassed, and that is Bulk Up, which in theory people say work's well, but in practice it really isn't as great as it is made out to be. A set with Drain Punch / Bulk Up / Knock Off / Sub or Safeguard might seem like an amazing set that can really break apart both bulky and offensive teams, but in reality it has a tough time setting up, and even after it has set up only being able to rely on Drain Punch for recovery does not make the set broken enough to ban.
TLDR: Gallade is outclassed in pretty much everything it tries to do, and it's one "decent" set really isn't ban worthy.
