AUB rewards like Olav are one time only - event SRs have the chance of coming back in a Witch Gate - Event URs have a low chance of coming back in Witch Gates per event - Summon Exclusive cards may or may not be put inside Premium Summon depending on the description given in the news (Dream Phantom was stated to be 1 time only and never returning as a card in future)
