The first wave you will need a dps with high stats I used squire with a genie pet for blood rage ability and to have capped mana for build phase. (7100 hero damage.)
Blue arrows are cloud directions.
First wave build auras and the 6 orc minions north.
You will have to run around with the tiki and normal ogre north until they both die during first wave. (it's tricky you have to be close to the tiki or he will run off and kill core.)
Second wave build the rest and swap to a TB monk and a wheeler/upgrader jester.
