Suggestion: drama masks

Item: two masks, the comedy and the tragedy masks (2 items) Useage: perishable items can be used only once. Once placed in towers, the two towers swapped with all their property and items after 60 seconds?? And the items are destroyed forever. Not much use i guess. But i sometimes wish that my carry tower was in that spot, so that i can change towers and utilise the range.

Nice, I like it! Switching towers would be sweet. Put it on my todo list.
