I don't like the Shell Smash meme so I go with max def max so attack EVs with leftover in speed, +def -attack nature and pack
Scald
Rain Dance
Ice Beam
Body Press
This allows me to tank almost any physical attackers and try to spread burns with Scald. My Blastoise has Rain Dish and holds leftovers so if I get a Rain Dance up he starts healing a lot per turn. Ice is obviously just great and useful coverage in general and so is Fighting, but I must admit Body Press is the move I use the least out of the set. The chip damage I'm capable of setting up with Gigantamax between Max Cannonades water vortex and max hailstorms hail can definitely fuck over an enemy, while Rain Dance still gives me access to Max Guard. If I do set up a Rain Dance and THEN Gigantamax it's awesome for the special attack boost, as well as the double Regen while the opponent dies from the water vortex.
Its proven consistently useful for me at the very least.
