Cards not working

For months my “if there are no copies in your deck” cards don’t work, my opponent cards are always working!! so very frustrating!! And I just don’t have copies!! Any tips?

do you have any replays?

show your deck code …

The Badlands cards with that effect were changed a while ago to check if your deck STARTED with no duplicates, instead of checking for duplicates when the card is played.

No, I don’t have any replays

then just copy the code of your deck
