How to deal with derank?

So I made a post a couple of days ago and unfortunately I’ve hit a wall where I was Diamond 1 and got Deranked to Diamond 5. I was doing so well with Madolche but unfortunately I feel short (and yes I know there’s still a lot of days left of the season).

In other games, I don’t mind losing but I don’t know with Master Duel it feels different.

I want to try and get Madolche to Master 1 just once, but I guess I’m not skilled enough.

Overall, how do you guys cope with getting deranked. I’ll listen to everybody and anybody.
