# Rillaboom #197/189 — Darkness Ablaze

## Summary

Rillaboom is the Galar Grass starter, and its drummer-gorilla design keeps a loyal fan base. The Voltage Beat ability made it a Grass deck staple in its day, and a Secret Rare slot at the top of Darkness Ablaze keeps collectors hunting it. At a $7.36 modelled guide, flat over 30 days on 59 copies traded, with 52 days of inventory on the board, this printing is almost entirely collector premium, since the same card plays for $0.16 out of Twilight Masquerade; a PSA 10 brings $56, 7.6 times raw, but a 73% gem rate against $85 of fees makes grading a losing trade.
