If only I had the time to grind the leaderboards maybe it would be possible. But right now, I've changed my rented cards. I started prioritizing cards that I would actually use instead of renting cards for power. I'm working hard to increase my winrate after grinding casually without caring about it since I started and taking notes for renowned LB players like Hyde and Kira. I've also joined my first tournament! It's still ongoing, but I'm taking notes and steadily making progress. Hope to see you in game :D
