I don’t really use mine much anymore. Water pulse is such a trash move and It’s really hard to fit in a team. I feel like it needs Toxicroak, medicham, or DD. Hypno works too, but forces you to stay in against gunfisk, which requires everything to go right. mindlessly throwing it into team is no bueno. All of those options outside of hypno is pretty bad vs grasshole too. I see that a lot lately.
On the positive there’s plenty of teams that just lose to it on the lead. Opponent swaps out of a bad lead, dewgong sticks around and throws an icy wind to chip and keep switch. Very hard to come back from. I use mine exclusively in the lead for that reason. I’ve seen people use it as a swap as well.
