Card Rulings talk:Covering Fire

what would happen if your opponent attacked a lv 2 monster, you use covering fire on your junk warrior? would your lv 2 card and junk warrior gain infinit attack points because there is no mentioning of ORIGANIAL ATK points (because lv 2 gains ATK = junk warrior + junk warrior gains attack = lv 2 cards and vice-vercer ........ what do you think?
