But you don't have any way to search for sites. In addition, even site lockouts need to be able to stand on their own two legs. Woman at the Well, Hopper, SWJ, Hur, TAS, and Mayhem can all create LS's outside of Sites during your opponents turn, and you have no way of blocking those RA's unless you get lucky with JiP or 2PBD not being Negated (provided you have a chance to play them before the CBN battle-winner most of your EC's will give them initiative to play).
