Hatterene's got a cool movepool but I feel like there's some things it definitely should've had. It's shown to Teleport a lot, it moves around that way in the overworld already, so why didn't it get to learn that move by default? Should've also had Hex, but that's more just because I feel it fits with her Witch theme.
Nice been a while since i saw a new Scribba. Movepool wise +Toxic, Bitter Malice, Doom Desire, Scald, Synchronoise, Ominous Wind, Signal Beam, Hyper Voice (Unironically) Yes many of them would be event level but id put them on other Pokemon if i could.

Hyper Voice would be kinda funny on it if only for the irony.
