Hi I have been farming my Z ring's and just beat the tournament with a psychic team and was not awarded the Z ring after 11 straight wins.
Correct me if I am wrong but here are the mechanics:
1) You need 2 teams, 3 of each which carry 1 common typing. So I.E. 3 psychic types, and 3 bug types and shown in the photo
2) They do not NEED to all be level 100, but will be used against PvP teams level 100 of specific typing
3) In order to qualify for your ring you must win 6/11 of the 11 matches using your specific typed team of choice. So If i wanted Psychic Z I must win 6 of my 11 matches with my psychic team and the remainder can be done with the others.
I have beaten all 11 matches and won 6 out of 11 using a psychic team of Victini / Mega Alakazam / Mew and was not awarded my Psychic Z crystal nor could I buy it on the shop for PVE coins. Please help this is annoying
