Let Loose is listed as Ability. When you play this Pokémon from your hand onto your Bench during your turn, you may have each player shuffle their hand into their deck and draw 4 cards. The attack Shadow Punch lists 30 damage. The cost is Psychic, Colorless. This attack's damage isn't affected by Resistance. Weakness is Darkness ×2. Resistance is Fighting -20. Retreat cost is 1. The flavor text reads "Able to conceal itself in shadows, it never appears before humans, so its very existence was the stuff of myth."
I keep a set binder for Shining Legends, meant to hold every card of that set. This card is one slot in the Shining Legends set binder. A generation binder holds one card of each species. Marshadow can fill a slot in Generation 7 binder (Alola). I still need this card.
