You can have all cards, but if you can't predict and counter your opponent you just can't go higher in leaderboard. You need too have positive win ratio let's say min. 51% and play many games. Or less games and 55-65% win ratio, which is not easy anyway. 😉

Many people not pay much attention to last games, they are tired and blindly play whatever they like. 😏

Anyway playing in high champion takes many time to find opponents 🥶
