Not able to use new deck to practice with my past game !?!?!

Dear CR team,

I just realise that I cannot use other deck for training on my past game. I am only able to use the deck I played with. But I remember that I used to be able to use other deck to practice on my past opponents. What happen to clash royal?

With Regards
Vinny

Try changing your game mode to Trophy Road and picking your desired deck from there.
