Wild Terastal Pokémon
(..just for future reference??) I think there should be a distinction between Terrastillized Raid Pokémon, and wild Terrastallized Pokémon (those with a glow).
I believe the latter always have a non-level-up move of their Tera Type, e.g. I have a Grafaiai with X-Scissor, a Growlithe with Dig, a Jigglypuff with Water Pulse, and a Tauros with Wild Charge (all of which are TM moves).
