Trevenant & Dusknoir Tag Team GX Box in October! By: Water Pokémon Master Posted 2 years ago to TCG 18 comments We finally know who will be joining Trevenant on its Tag Team card! We can announce a ghostly new “Trevenant & Dusknoir Tag Team GX Box” will release in America and Europe on October 25th to celebrate Halloween. It will retail for $19.99 and come with a promo Trevenant & Dusknoir-GX, a jumbo version of the card, four booster packs, and a PTCGO code card. No Trevanent & Dusknoir-GX has been announced for Japan yet, so we have no idea what the card does or what it looks like. It will have to be a Psychic-type since both Pokemon share the Ghost-type.
