While playing Artanis in BGs solo queue I chose Reflective pendant as my lesser trinket and only got Imortal (hero power minion) from it for rest of game. Ended up with 3 golden imortals (9 imortals total 8 obtained from reflective pendant).|
This is extremely strong as the scaling is exponential where each of the imortals doubles stats of the previous one.
I cannot rule out I got lucky 8 times in a row but the probability of this happening is so low it leads me to believe this is bug.
