Just to make sure.... You MUST save your profile to keep the unlockables. I won the Elite World league, and then started playing against the Lions in a tour. Played one match, saved it. Came back it the next day, and I could not play against them. I had to choose the Lions. Then I realised I had clicked "No" on the pop-up asking me to save, thinking "I will save it later".... Stupid stupid stupid....
