for pure plunder its rather easy , pure housing infra , some kind of baseworld you cant cluster ( 2 land U spaz is best )
then fight , cluster anything you feel like , ensure you can rpotect the stuff , then when you get dp pop it all up and plunder , then repeat
or do it while fighting so that fighting also increases your pop and lets you plunder before you even get dp at times , you can alter the style alot but yes , the basic for plunder is
fight , make room , fight + pop &/or plunder at will
