Azumarill makes a return with its sub punch set from 4th gen, working fantastic again as it gives it more staying power. Evs and nature are standard for all azumarill sets, as is its ability, substitute is the key to the set as it lets it avoid being forced out by pokemon such as rotom wash and grass pokemon like breloom, while allowing it to resist status moves. With a substitute, azumarill can use waterfall over aqua jet, dealing twice the damage, while play rough fuctions as a secondary stab, as well as a coverage move to hit threats that formerally walled it such as rotom wash and gyarados, while focus punch makes use of its substitute to deal massive damage to steels without the draw back of superpower. Azumarill has trouble with four moveslot syndrome, being walled by grass/poison and water/poison pokemon and wishes it could use return and ice punch, but does a good job with the coverage it has.
