This is a Great Strategy.
What you need is:
Dark Door
Sinister Serpant

	That is all you need. All you have to do is play dark door and have sinister serpant out.  You and your
opponent cannot attack with more than one monster. Then when they attack your sinister serpant
when its your turn all you have to do is use its effect and take it from your graveyard place it in your
hand and play it again.
	Hint: Make sure you have something to stop them from destroying your dark door.
