Its a handy addition to the minimal roster of Steel-type Pokemon and helps bring some extra value to cards like Melmetal which has a rather steep Energy requirement for its 120 damage attack

However, while strong, its also a card that can be hard to use, in terms of things like needing three types of EnergyFire, Water and Lightningto attack, and having to return it to your deck when you use the TAG TEAM GX attack

Even without topdeck manipulation, you can still do stuff like bin Portal to Phyrexia and then wait for the Refurbish to end the game on the spot
