This rarely happens but when it does it is sweet!

There are actually 2 ways. the harder way is to go first and draw exodia in your hand but obviously the chances are like finding a needle in a haystack.the easier way is to go second,let him play magic,trap,monster,whatever he wants,it won't do him any good.when it is your turn draw heavy storm,raigeki,cyber stein and megamorph,plus have a blue eyes ultimate dragon in your fusion pile.

(can get in blue eys ultimate dragon pack)use the heavy storm to get rid of the magic/trap cards,use raigeki to get rid of the monster(s),then play cyber stein and activate the effect then choose blue eyes ultimate and use megamorph so b.e.u.d. has 9000 attack!!!attack his lifepoints directly and you win!
