1 GSR booster is sufficient for me to secure top 300, so in this case, the only issue is whether you can efficiently use the booster in EH with a strong MH.

In my case, most of the times I try to grind as much as possible for the keys before EH comes out to secure sufficirnt keys throughout the event, but this event might be abit of a difficult choice as you'll have to balance the EX area drop grinds and the bonus area grind.

Hence, I usually just spend some ultimate summon tickets to get a pair of the booster SR for this type of events.
