Orochimaru works fine with agk actually if has the bond skill and is full sb. (has the perfect chase for her and is boosted by her + kills with mystery any ninja that she left alive and if the barrier is up her and the other characters you use would be actually way way harder to kill). It fully counters edo hiruzen teams for example if you own overall initiative (since hiruzen with no barrier buff would actually hit low with standard and mystery on somebody with a 60% boost to both def and res)
