I suggested in another thread how matching vaults (three or more) could/would/should create a vault key, and how the matched vaults could/would/should then explode (or disappear from) the board, allowing for the cascading of new pieces from the top.
But, read the OP in this thread.
It shows what one person can do in Gems of War simply by playing one game mode.
