I use a magician deck. My problem is I can hardly seem to win. I know the rules of the game and I've played a lot, yet I keep losing. I always play against my brother and he's really good. Everytime we duel he usually uses a different deck. my strategy is to summon all 3 of my dark magicians and combine it w/delta attacker. My 2nd strategy is to summon my dark eradicator warlock and use his effect. Many of my cards have effects, most of which I use to increase my life pts. Can anyone tell what I'm doing wrong or what I need to improve in order to win? Thanks!
