It's great how Incineroar is up there with Lando, and all it needed was it's HA and a decent number of Tutor moves. We had a lot of practice last year with Arcanine, but now El Tigre brings much more to the table such as:
>A 95/90/90 defense that gets support with Intimidate, and is commonly given an Assault Vest to compliment it's sp.defense
>115 Attack stat is great for taking down glass canons that can't OHKO Tony
>60 Speed give it a chance in Trick Room
>Support moves like Knock Off, Fake Out, Snarl, Will-O-Wisp, Low Sweep, Taunt, Roar, and Throat Chop (if sound based moves are annoying you)
>Can take hits from Fire, Grass, Ice, Ghost, Dark, Steel, and Psychic
>Works well in a Grass/Fire/Water defensive core
A few downsides like making Competitive Milotic and Defiant Empoleon more viable, and being weak to Rock, Ground, Water, and Fighting (all very common types) just to name a few.
