I have noticed that when I am using certain game modes like single color, starter decks or especially jump in, making modifications to my deck I can use are suppressed. With jump in which I pay a fee for, I can edit the deck, but the changes are ignored in play. Yet the ones that play against me seem to be able to use whatever cards they want to. I limit how much I spend and do not enter other events often as I consider it like gambling which I avoid for obvious reasons. I play the free and lower cost events online as part of my daily mental stimulation efforts and I appreciate fantasy pets that are more like real ones and avoid paying for Mastery or store items unless I like what I see. I am asking for at least the jump deck changes to be something I can use in jump in or that the opponents be limited to the same as me. Otherwise, it is not fair.
