Swampert 4 is an excellent lead because it has virtually no weaknesses and can hit most things for big damage. It also gives general Psychic type insurance through Mirror Coat. Its lack of speed is compensated for by its bulk. Dodrio is a good partner for it because it can switch in on what Swampert is weak to and is then able to Endure most of the time. I don't like that Aero much on lead because being locked in can give rise to awkward pivoting situations, though the speed and power is obviously nice.
Leading off with Swampert is something I usually don’t do but it does make sense with water ground ice coverage + mirror coat being pretty bonkers. I also am usually disappointed switching that Mon in. However. I also feel like I have the defensive mons in the back TO switch Aero out on lead (Swampert for electric and rock and steel, LAPRAS for water and ice) I really like lapras here over Dodrio. Dodrio scares me to use with 31 IV’s because in the back mons might not see a kill on it and proceed to twave it and I hate having to endure and risking status effects idk lol. We will see tho perhaps my vision will change on Sunday! I also don’t mind Swamp lead with Aero/Dodrio in the back!
