Forum:Law of the Normal - Destroys face down monsters?

I was trying out a level 1 normal monster deck with "The Law of the Normal" being the core card, but when I used it, he argued that his face down monster is not destroyed where the card states "destroy all cards on the field except Level 2 or lower Normal Monsters" saying that I dont know if its a normal level 1-2 monster. Clarification on this please!Gingerbreadmon (talk • contribs) 01:14, March 15, 2015 (UTC)
