Memory Game in Storyline ideas

Hey there :) 

I am attempting to create a memory game in Storyline and the first step is to get the logic behind it right. 

Basically we have cards with a flipside. This can be solved by states. 

I was thinking to disable/hide the cards when two cards that fit together are selected. 

I thought this could be solved by just adding a script/trigger that works like: 

If x and y = selected: 
    change state of x and y to disabled

But this doesnt seem possible for one because you can't change 2 objects in one script. 

I am am now looking for ideas how to solve this. What are the triggers that should happen when I click one object? 

1) Change state of [object] to selected when user clicks [object]
2) What else
3) What else should happen?

I know there are examples but I am going to make this one barebones, no layers, no feedback slides, nothing like that :) 

Any ideas? :P
