Ok, I'm new at the game but Im not an idiot. I finally figured out how to defeat Blue Eyes White Dragons without losing any Life Points. First of all if there is a Lord of D. among any of the Dragon-type cards destroy it first, it may seem tempting to go for the dragons but the Lord of D. protects them against magic and traps. The destruction of the Blue Eyes is based on how your opponent gets them on the field. You can destroy about any of them if their summoned Normaly or through a Tribute summon with the Trap Hole trap card (make sure to have 3 of these on the field, remember your opponent can only have 3 Blue-Eyes White Dragons). If their Special Summoned (Flute of Summon Dragon) play the Dragon Capture Jar and then 2 Fissures or play Swordstalker with Sogen magic and 2 Reinforcements trap cards (use 1 Reinforcment per Blue Eyes White Dragon). You can also use Change of Heart to blast away the Dragons one by one OR to remove the Lord of D. Now it all depends on what you want to do with the Blue Eyes White Dragons. You could use Monster Reborn to get them on your side of the field or use the Soul Release magic to remove them from the duel permenatly. I recomend reviving one Dragon and playing one Lord of D. and a Hoshinigen then using Soul Release.
