I used seeds to run many battles back-to-back during 3-4 Burst hours. I have a strong team and strong friends so fights end quickly, even those that I join with high HP, and I can usually MVP to maximize ticket yield and farm more seeds. Since I got so many SSRs from Gatcha, I didn't need many Souls to MLB the SSRs.
I can also Auto fights effectively, but marathoning during Burst hour was more fun and less distracting.
