Ok this is want you need to do.
First have at least 1 card that has a good defense like mystical elf with a defense of 2000.
Then put her in defense mode.
If your opponet has a good monster out then attach some kinda card which increases defense like castle walls.
then after that add a book of secert arts. You need to put down another high defense card. Add castle walls to that too. soon you will have a ultimate defense. Put down some even card and use him in attack (remember if a monster is in defense mode life points will not be taken off).
You will soon have a high defense and you opponet will use all of their good monsters trying to kill your hi-defense monsters. Finish him off with some trap holes. BAM!!!!!!
