I just think it has too many combos and advantage rearing. During opponent's turn copy attacking monster and negate attack, tribute next turn to destroy it. Or just use that during your turn. This way, the card can't be used during their turn and still allows you to tribute it for something, but not at the expense of their monster.

Although I do agree with the fix. At least it can still be used for sycnh/tribute or just to ram for a very basic 1-for-1. /ok
