War Book used to be a multiplayer game on Facebook.
I played a Mongul and a Mage. Using the Mage to steal acres, and then have my Mongul to tap the Mage to increase my size.
Constantly tapping the Mage with the Mongul ensured that the Mage couldn't be retalliated by other players, and once my Mongul consolidates its defenses (by training elites), nobody would ever breach my defenses.
By focusing all on money making I could also send gold and supplies to my mage to help it sustain growth. The mage was focused on stealing land with sorcery.
These screenshots are pretty old and they don't show much. But my Mongul's forces were nearly 95% elites and i was within the top 30 players in the game, and top 3 Monguls.
