Forum:Lord of D. Vs. Ordeal

Say i have lord of d. and a horus on the field, and my opponent has a face up Ordeal of the Traveler, if i attack with my luster dragon, do i still have to go through the effect of Ordeal? if my opponent also has a face up toll, would i also have to pay if i attack with luster dragon? Would it be any different if i attack with a Horus LV6?
