# Rillaboom #016/167 — Twilight Masquerade

## Summary

Rillaboom is the Galar starter that won over drummer-minded fans and Grass loyalists, and toriyufu is a well-known name among illustrators. Its attacks give it a real place on a Grass deck, but as an Uncommon it stayed an ordinary pack pull, so demand comes from players and Galar completists. A $0.15 modelled guide, up 36% over 30 days on 44 copies traded, says bulk, with 737 days of inventory on the board, and the economics stop there: PSA does not split this card’s population by finish, so no gem rate can be read for it.
