That jerk Hau ambushed me for a Pokemon battle, giving me no chance to decline, or switch my team, or anything. He healed my team at least.
Round 1: my Hariyama vs his Raichu. It was an Alolan variant but I didn't know anything about it. I opened with Fake Out, then tried to use Knock Off in case it was holding something nasty. Well, it turns out that Alolan Raichu are psychic, and it unleashed a powerful STAB supereffective attack...and Hariyama survived with just 1 HP! Knock Off connected, was also super effective, and Raichu went down.
Round 2 was where things got messy. Hau sent out his starter, Brionne, and I countered with Petilil. Brionne got off a Bubblebeam before falling asleep, after which Petilil restored almost all of her HP with Giga Drain. She was in the middle of throwing out a Leech Seed when Hau swapped Brionne out for a Flareon of all things. The fire fox got seeded instead, and I switched in Munchlax for her Thick Fat. Leech Seed remained active, letting Munchlax easily stay in the fight long enough to crush Flareon.
Round 3 was back to Petilil vs the still-sleeping Brionne. Another Leech Seed went out, but then Brionne woke up and unleashed a Z-move! It left Petilil with less than half her HP, which might have been worrisome had Petilil not connected with a second Giga Drain which easily scored the win.
