Nelnal has been credited on Pokémon Trading Card Game artwork since 2023, with cards appearing through 2025. Their illustrations are most frequently found in the Scarlet & Violet series, including Paldean Fates, Scarlet & Violet, and 151, with an additional appearance in the Sword & Shield era via Crown Zenith Galarian Gallery.
Across these cards, Nelnal’s approach is largely cartoonish and playful, with cheerful, lighthearted moods and energetic pacing. Compositions tend to read as balanced yet dynamic, keeping the subject clear while using bright, vibrant color palettes that often lean harmonious or pastel. A representative example is Toxtricity (Crown Zenith Galarian Gallery). Among the most sought-after cards illustrated by Nelnal is Riolu (Scarlet & Violet 215).
