@ashikstd Thanks for de comment.

As I have told @dewabrata , I had my rented cards and I had already canceled them to have them back on the last day of the season, but there were still a few hours to go.

Previously, as I also pointed out, I had seen other people do something similar, and as I say, I did not know if there was any kind of problem with this, just as many people publish challenges with other cards to be among the first, I think this should be reviewed Also, since the challenges are requested with common or rare cards that are included in the spellbook, the excuse that you do not have that card is not much use.

That said, if it is considered a bad practice, it will not be repeated, greetings.
