1: There is no strategy. Plain and simple. You just need to know how to knock somone into a deathtrap to win.
2: To kill off a champion, place a deathtrap, and teleport HIM on it.
3: ALWAYS make your pawns into your best character.
4: Spells will end up useless, just make the game seem longer.
5: Kill everyone until killing the leader to get the most Koins.

Chess CAN be fun! :)
