Provenance

Where it came from

Sigilyph-GX 98/214 was released in the November 2018 expansion Lost Thunder, which was the largest set in the Pokémon Trading Card Game at the time of its debut. The card features the avian, psychic-flying type Pokémon introduced in Generation V, rendered in the hyper-stylized, metallic foil aesthetic characteristic of the GX era. This iteration serves as a mechanically distinct card designed for the competitive landscape, emphasizing defensive utility through its ability to prevent damage from non-Ultra Beast Pokémon.

The artwork for this specific card was illustrated by 5ban Graphics, a prolific studio known for producing the majority of Pokémon GX and V card designs during this period. Their approach focused on emphasizing the geometric, ancient motifs inherent to Sigilyph’s lore while utilizing the glossy, embossed surface treatment required for Rare Holo GX cards. Upon release, it was well-received by players for its specific strategic niche in controlling slower-paced matches, standing out within the expansive 214-card checklist of the set.
