Psyduck seems like it has it's niche. 100/104/96/130/100/110 is a little slow, but it has pretty solid bulk. The best part is its ability, cloud nine, that allows it to get past desolate land and smack groudon with a powerful water type move. Plus it can switch in on a lava plume decently. Actually, sub calm mind with scald + psyshock seems amazing. It OHKO's primal groudon before any boosts, and with 2-3 calm minds it beats a lot of primal kyogre sets. Not to mention if scald burns, it becomes ungodly tanky.
