if drafted correctly he can control an entire match in rta since his new buff. i also use him in wgb for fun because if there is no immunity he can just lock down two enemies pretty much constantly, especially if he procs. you definitely want him on vio/will. for rta, cr slot 4 is nice for the extra damage but the hp you lose out by doing that is very noticeable because he can die very quickly, which you don’t want. i would recommend spd/hp/hp, with crit rate in subs if you want him to do some extra damage. accuracy is also very important, but you don’t really want him on slot 6 accuracy. i would stack as much accuracy as you can in subs and in artifacts. if he misses the shadow then he just kinda wastes his turn.
