Congratulations! 💪 Reaching Champions league is not easy nowadays.
I wouldn't worry about not playing the first day of next season because it's the worst day to play: The reward pool is empty (supply of DEC come on the 2nd day of seasons) and it's a struggle because everyone tries to rush it to get to the top as soon as possible.
You're gonna make a lot of money renting out your cards on the last day 😄
