for this you need the following:
dark hole
call of the mummy
zombie commander
zombie tiger

this is a simple strategy that can take a large portion out of your opponnent's life points. all you have to do is have dark hole and call of the mummy waiting to be played until you draw zombie commander and zombie tiger. both cards are searchable by sangan or a witch of the black forest. once you get the cards needed activate dark hole and destroy all the monsters on the field, next activate call of the mummy allowing you to special summon a zombie from your hand. since zombie commander is both a zombie and union creature play him. his special ability to special summon a zombie tiger to the field when he is played face up doubles your forces but that's not all.  you can equip zombie commander to zombie tiger and make him 500 atk/def points stronger making him a 1900/1600 attacker with your opponent's life points wide open. in addition, when you do battle damage you can destroy i card randomly from you opponents hand, this could be good agianst exodia. as well as the many cababilities i have explained once the duo is destroyed only zombie tiger is destroyed leaving you a monster to put in defense mode or sacrifice for a stronger one you just drew from the deck. that is all, i hope this helps someone.
