You already got it. It comes out in November. It’s star attack is 200 for [G][W][C][C], but it can’t attack during the next turn. The GX attack puts 3 of any Dragon type Pokémon from the discard onto the bench.
Would sigilyph be a good one of in some psychic decks? The attacks dont seem very good, low damage for the regular and the gx being a one time thing. An unusual weakness for a psychic type. But if the opponent has to be cautious because of the ability...well, I guess that isnt much of an issue with guzma...hmmmm...maybe on second thought it's a no go?
