>>27537141Tangrowth has Knock Off and Regenerator, meaning it has both of the things that separate Mega Venusaur and Amoongus.
Quagsire has very good typing, a good ability, and just enough unpredictability to keep an opponent on edge.
Maneton is faster than Zone.
Alo is just fucking fat.
Sure, many of these Pokemon may be generally outclassed, but they all have just enough tools to be worth a damn.
Hell, even Feraligatr, who is seen as a diet Gyarados, has Swords Dance and Aqua Jet to set it apart.
