You can bounce an annoying 'walker that slipped through your counter shield and then Counterspell it on return
For a card to work well, especially the more complex ones, try to have abilities that work together or seem to have some cohesion
If such an ability requires a target, you can target a Room even if both of its doors are unlocked, but the ability won't do anything when it resolves
