I would team up with Matrix and turn on the one of your neighbors.
My favorite play is the whoops attack.

Have Matriz, or the other guy declare war, wait 5 turns until the troops move, and then powie!!

Hit the weakened back lines quickly taking 1 or 2 cities. Everyone around will attack like sharks on bloody chum.

Spawning an artist really makes this effective.
