Defeated this leader who showed again after a month with his new shadow cloud (defeated in oneday).

So this leader comes with his face every month or after a season with different shadow pokemon but can't give a good iv one ,not his worker (chele) or grunts like I am frustrated with these ivs giving this much time to this and getting this in return I just want to cry. Btw this was my fastest research I have done so far of taken over and any other research I have lol.
