Sorry for the loss OP.

Maybe not what you want to hear right now, but I’m really glad Steam cloud minimises the impact of a loss. When I had a Nintendo Switch I was terrified of losing hundreds of hours of Dead Cells or Enter the Gungeon progress. Losing a Deck is obviously a financial loss (and the emotional attachment of someone special giving you yours), but at least there isn’t insult to add to the injury the way Nintendo would do.
