"CURSE OF ANUBIS" This Trap Card has a lot of utility. It does affect Effect Monsters on both sides of the field, but you can work around this. One good use is during your opponent's Battle Phase. If your opponent only has Effect Monsters, and they declare an attack, chain your "Curse of Anubis". Now all his monsters are changed to Defense Position and cannot attack! For a more aggressive use, set "Curse of Anubis" then activate it next turn before you Summon. The opponent's monsters will be changed to Defense Position and have their DEF reduced to 0 points. Now Summon your monster for the turn. Since you activate "Curse of Anubis" first, your new monster is not affected by it. Now you can attack the opponent's monster and destroy it. - click here for another Dueling Tip.
