Starter Pack cannot participate in conflicts.
In addition, if a large number of card packs are opened, more legends and GFs can be obtained from booster packs based on the expected value of the potion.
Legendary card packs and GF card packs mainly feature 6x and 3x conflict bonuses, and it’s kinder to people whose open pack are lower than expected value.
