Use this and then chain Wall of Disruption. The monster loses the attack, and then is banished immediately, but will not retain the reduction when you control the monster. Wall of disruption in this case instead reduces the damage you take, and reduces the attack of your opponents other monsters, if any. However, it is a two card trap combo that clogs up backrow and is on the expensive side cardwise, so take this how you will.
