Zeraora GX

This is the 4th most valuable card in Thunderclap Spark out of 73 priced, so there's genuine scarcity appeal here beyond the GX tag. Don't expect much movement at £15.22 unless you're hitting the right collector—Japanese Pokémon GX cards have cooled considerably from their peak, and this one will sit unless you price it sharp or bundle it with stock that moves faster.
