We've been on a streak of really good gym battles since Driftveil, and another one added here. I'm glad we got as assortment of uncommon attacks in this episode (Astonish, Aurora Beam, Brine) and Scraggy getting his debut is nice. I'm also happy that the "Ash only uses 2 Pokemon" rumour was false.
Love the foreshadowing with Iris at the end. I think there's more to her backstory with Drayden.
