I was playing World Tournament 2007 the other day, and I couldn't help but notice that when my opponent used Ruin, she only destroyed 2 monsters instead of my whole set. I tried it myself and i could only attack twice, even if there were more than two monsters on the field. But i thought that after it destroyed a monster by battle, it could attack once again in a row. I know it says once, but doesn't it's effect go again after you attack another monster and destroy it. Or else I owe alot of friends apologies on destroying their field:D

Apparently you owe apologies because her effect (just like BLS) can only grant one extra attack.

after it destroys a monster you can attack ONCE again in a row. not everytime you destroy a monster. just the first one. so like bls you can only attack twice.

LOL....good luck in your apologizing.
