# Greninja V-UNION #SWSH155 — SWSH Black Star Promos

## Summary

Greninja V-UNION is a promo that only comes together by collecting four separate pieces, which makes a finished set a bit of a chore. Greninja's place among the best-loved starter evolutions, plus Shin Nagasawa's long Pokémon illustration career, gives it steady collector appeal. The modelled guide sits at $5.68, down 4% over 30 days on 15 copies traded, with 115 days of inventory on the board; PSA has slabbed 145 of these and 100 are 10s, a 69% gem rate, but no graded market has formed to price the slab, and the slabbed population is growing 2% a month, faster than 90% of tracked cards.
