My idea was that when you place a block in the menu where you select colors there would be a False-Block color, The False-Block would vanish when it is stepped on or hit after 2 seconds [?] making a crumbling noise as a warning. The block would cost 10 Blocks to place and gives 5 [?] blocks if you delete it.
Pros
Players can make elaborate traps
It would help with defense
It would encourage players to pay more attention
Cons
It could be spammed
It'd make intel capping harder
You would have to sample the terrain to switch colors
Thoughts?
