What Is On This Card?

By drumming, it taps into the power of its special tree stump. The roots of the stump follow its direction in battle.

How To Research This Printing

Start with the image, SWSH Black Star Promos set name, and SWSH006 / 307 collector number. Those identifiers matter more than the character name alone because the Pokémon TCG can reuse names across reprints, promos, alternate artwork, and later expansions.

Next, match the finish and condition. A holofoil, reverse holofoil, unlimited, or first-edition listing may carry a different reference price even when it belongs to the same card printing. Grading adds another layer: raw marketplace references should not be treated as prices for PSA, Beckett, or CGC slabs.

Finally, compare the visible update date with current marketplace listings and recent sold results. MonZap gives you a fast catalog reference, set context, and scanner workflow, while the linked marketplaces help you check what is available right now.
