If you want one, here it is: max iron maiden (IM), max bone spirit (BS), and get as many revives as you need. Throw IM on everything that moves, and revive anything that doesn't. When this doesn't work, spam BS. If you want to be fancy, you can use poison nova to stop monster regen, bone wall against ranged attackers, and TP to town constantly to heal so that you can shoot BS all day. Do this long enough, and you'll be on the ladder. Then you'll assume you have the game completely figured out, get bored, and leave. Good. Good-bye.
