Tinkatink, Tinkatuff, and Tinkaton are all blacksmiths, so they would know how to recycle materials for new projects, hence why I think they should get the move Recycle.
It could be used to give them infinite Big Nugget Fling, for example, which would give them a base 130 power Dark type move every other turn.
Sure, that is weaker than Gigaton Hammer, but it is still pretty powerful, and offers type coverage. (Whether it is good coverage or not, I don't know, as I'm not a part of the competitive scene.)
But also, you could Recycle Fling a Light Ball (guaranteed Paralysis (except against Electric types)), Flame Orb (guaranteed Burn (except against Fire types), but you'll get Burned too on the turn you Recycle), and so on. For a fuller list of all the stuff that can be done with specific items and Fling, please look at the Bulbapedia site for the move Fling: https://bulbapedia.bulbagarden.net/wiki/Fling_(move). Could be very useful for a support Tinkaton.
As a bonus, if Steel Gems come back, you could use Recycle on the Steel Gem, since you already can't use Gigaton Hammer two times in a row.
I just really like this idea, okay. Let me know what you think.
