# Yveltal BREAK #66/114 — Steam Siege

## Summary

Yveltal BREAK came from a format where Yveltal decks were already a constant, and the BREAK treatment gave that archetype a bigger-hitting, benched-damage option. As Gen VI's Darkness box legend it keeps real fan loyalty, and 5ban Graphics, a prolific studio on the Pokémon card line, adds to a mid-tier Ultra Rare pull. The modelled guide sits at $7.43, down 1% over 30 days on 89 copies traded, with 240 days of inventory on the board; the slab is the real edge, with PSA 10s at $425 and a 53% observed gem rate putting about $100 of expected profit per submission.
