I won't talk about the main card, but only about the collocation of the auxiliary card and the four-leaf clover. Auxiliary cards are all good cards (three-line wine rack is recommended).

On the 6: 4 star good card+three-level four-leaf clover;

Score 7: 5 star good cards +4 star good cards +3 level four-leaf clover;

8: 6 star cards +2 5-star cards +3-level four-leaf clover;

On 9: 2 7-star cards+1 6-star cards +4-level four-leaf clover;

On 10: 9-star good card +4-level four-leaf clover;

Shang 1 1: 10 Star brand +4-level four-leaf clover;

Shang 12: 1 1 xinghaopai+grade 5 four-leaf clover;

Go to 13: 12 xinghaoka+level 5 four-leaf clover.

It will get twice the result with half the effort to choose a service area and time period with few people for comprehensive reinforcement. In case of continuous explosion, remember to stop and have a rest instead of scoring continuously.
