Mage Secrets Not Working in Dalaran Heist?

[Tupi 30]

Just today I've noticed that one secret in particular is not working.

"Duplicate" did not work several different runs and just now I had 4 or 5 cards killed w/o it working.

Are you having them killed by trading on your turn?

Because secrets only work on your opponents turn, which means your opponent has to kill your creature.

 

I can tell you straight up that the secrets work in Dalaran Heist as they're intended to work.

nope, as of that original post, i had that one secret not work several times on subsequent rounds after the cast.

i'm aware they don't work on the round cast.

I haven't played mage again since to check...i only play maybe 1 run a day...
