Do you mean you want one card duplicated three times, and you want to be able to change just one and have the other three change in exactly the same way?
If so, then smart objects may be the answer. Set up your 2 x 2 grid, and make one card. Then, with that card’s layer (or layer group) selected, choose Layer > Convert to Smart Object. Then duplicate* that smart object three times so that you have four of them, and lay them out.
When you want to make a change, double-click any one of the four smart objects. It will open into a new window. Make your change, save, and close. All four smart objects will be updated.
*Duplicating the smart object using the Layers panel, Alt-drag with the Move tool, or Layer > Duplicate Layer will work. Do not use Layer > Smart Objects > New Smart Object via Copy, because that creates a disconnected copy.
