# Maintenance (Japanese) #079 — CP6: Expansion Pack 20th Anniversary

## Summary

Maintenance was a quiet staple of XY-era Item decks: shuffle two cards from your hand back into the deck, then draw one, a cheap way to smooth a hand. On this Japanese reprint, two jointed robotic arms pass a glowing Poké Ball across a green gradient. It arrived in September 2016 in CP6, ahead of the English Evolutions set that November, and as an uncommon it is a modest pull. The modelled guide sits at $1.99, flat on asks over 30 days with no copies traded; no PSA population is on file.
