Key cards

GX cards: Zeraora-GX (Lightning type) headlines the set with its Thunderclap Zone ability, which gives free retreat to any Pokémon with Lightning energy attached. Deoxys-GX (Psychic type), Scizor-GX reprint, and Suicune-GX (Water type) provide additional GX power. Each has RR and SR versions.

Notable cards: Electrode Prism Star, Thunder Mountain Prism Star Stadium, and Viridian Forest Stadium are competitively relevant trainer cards.

Secret Rares: Zeraora-GX SR and HR are the primary chase cards. UR gold trainer cards complete the secret rare lineup.

What is in the box

A Japanese SM7a Thunderclap Spark booster box contains 30 packs of 5 cards each. The moderate card pool gives reasonable odds at pulling the Zeraora-GX chase cards. SR and HR pull rates average roughly one per box.
