New Bublik tournament

The Bublik Open or whatever it’s called. You have to win the whole entire thing just to get 10 Bublik cards. And you know the leaderboards will be filled with all 20/140/140 people anyway and I don’t have the gems to redo all my matches like that. Is it even worth it or should I just focus on the tours and club matches?
Honestly I am having a hard time decided if the “special events” are ever even worth it. Thoughts?
