This year's World Cup has a new unbeatable tactic after changing the rules.

Because the expanded tournament allows more teams and relaxes the rules for physical confrontation.
A popular style is similar to the tank formation in Honor of Kings:
Iron bucket defense chain formation.
Morocco and Australia made good use of it.
Both are weak teams that either drew or beat strong teams.
Japan saw this and also learned to play the iron bucket formation.
Against traditional imperial teams that rely purely on skill (assassin style).
If we compare the iron bucket defense chain formation to Honor of Kings:
As soon as the veteran imperial team's core shooter (assassin) gets the ball,
those playing the iron bucket formation: immediately transform into
Nezha flying at you, Lianpo hitting you, Bai Qi using his ultimate to taunt you (kicking your foot),
there's also Liu Bang passing Nezha, and Yao on top of Nezha's head.
