# Dark Patch (Japanese) #029 — Master Deck Build Box EX

## Summary

Dark Patch in this Japanese set shows a pale, pitted oval against a deep blue swirl, a plain gadget in a card that is nearly all grey and blue. It is a Goods card that fed Darkness Energy to the Bench, a staple for the era's dark decks. Its English home is Dark Explorers, released in May 2012, so this Master Deck Build Box EX copy from September 2012 arrived months later.
