Although its aesthetics and rarity are the main drivers of its value, the card was also known for its immense potential in competition
Cramorant [Lost Origin] can attack for free when there are four cards in the Lost Zone, Mirage Gate can accelerate Energy once you have seven in the Lost Zone, and Sableye unlocks Lost Mine at ten cards in the Lost Zone
You can get pretty dirty with this thing, especially if you can get infinite combats

The synergy of competitive utility and jaw-dropping art is what has pushed this card into the top tier of value
