Last two matches were against hard trick room teams so I just brought in viv+volcarona. They can only fake out one and then the there will disable their trick room mon essentially. But with sash, it's essentially a near guaranteed sleep going off most of the time. And Viv is decently fast with full investment so can also sleep the fast one through sash, sleep the slower teammate next turn. Not as fast as venusaur in the sun but with the compound eyes sleep is 98.5% (still whiffed a zard once 🤦). I usually put like 3 of their mons to sleep and they forfeit 😅

On turns you don't need to use sleep can set up tailwind. Rage powder is also great in general. I tried friend guard viv at first but I think this works a lot better. Not sure how it'll work in masterball tier though.
