Epikasta Rigatos and Mask of a 1000-faces

Is there a distinction between playing an action and performing an action?

In this case, if Epikasta Rigatos plays a Kine Resources Contested and Foureyes plays Mask of a Thousand Faces to take up the action and is not performing the action instead, can I shuffle the Kine Resources Contested back to my deck after the action?

I don't see anything conclusive in the rulings for either card.
