Clefable: Mundane. Potential, but mundane.
Malamar: Interesting. Of course, there is a chance that your opponent won’t have a Pokémon in hand, but if they do: It depends on what your opponent is playing (a Tapu Lele GX in hand won’t be much help) and most attacks are situational, like Blacephalon, and can’t just be used willy-nilly. The fact that it DISCARDS that Pokémon is actually pretty good, considering then your opponent has to find a Rescue Stretcher. And you look at your opponent’s hand, which is a big advantage. It’s interesting, but depends on the metagame. I’ll be keeping my eye on this one.
