I encountered this in a Tavern Brawl that I played with a friend. I had picked Masked Ball (minions played gain deathrattle to summon minion that costs 2 less). She had chosen Burgled Spells (casting spell summons random minion of the same cost).

She found Explore Un’Goro, decided to cast it for the memes, was able to discover “Dr. Boom, Mad Genius” from one of the Choose Your Path spells, and obviosuly played him. That was on her turn 13. And then on turn 14 and 15 we noticed that when she played another spell, she would receive two random minions of the same cost instead of just one.

Looking at the replay source, it appears another copy of TB_100th_001 (Valeera's Bag Enchant) was created and attached to Dr. Boom, without removing the old one. Unclear if this affected other brawl options.
