I doubt the battle will be easy in favour of any particular side. If we assume that each Royal Guard officer has reiatsu equal or similar to Yama-jii (which they should considering Shunsui's claim about them) then it shouldn't take more than one of them to match/neutralize Haschwalth and again for Uryu even with the special reijutsu present. That would leave another three all for Yhwach.
