# Mermail King - Neptabyss Neptabyss represents a key enabler in Mermail deck strategies, functioning as a searcher that smooths consistency. Collectors view this card through the lens of competitive viability rather than raw power, since its utility depends heavily on the broader Mermail archetype's relevance in the metagame. The Quarter Century Secret Rare variant carries significance as a premium treatment, appealing to collectors who prioritize aesthetic presentation and rarity. However, the Ultra Rare version remains the practical choice for players, offering identical functionality at a fraction of the cost. Most collectors balance between owning the secret rare for collection completeness and the ultra for actual deck construction.
