Crystal Beast Ruby Carbuncle

The Crystal Beast Ruby Carbuncle was originally introduced as part of the Force of the Breaker expansion in 2007. As a pivotal monster in the Crystal Beast archetype, it was designed by Konami to facilitate the special summoning of other Crystal Beast cards from the Spell and Trap card zones, acting as a crucial engine for the deck's swarming strategy. The character's design reflects the vibrant, gemstone-themed aesthetic of the archetype, intended to make the monsters appear both magical and crystalline.

The Hobby League 5 participation card release, designated HL05-EN001, was a promotional iteration distributed through organized play events in the late 2000s. These cards were awarded to participants in local shop tournaments to encourage competitive engagement. This specific version features an Ultra Rare holofoil finish, a rarity tier highly sought after by players of the era for its distinct, shimmering presentation that contrasted with standard set releases. While the card's mechanics remained unchanged, its presence in the Hobby League series cemented its status as a staple in the duelist community.
