Talk:Relena Training Event!/@comment-217.211.169.29-20170224001826

Hi! I have super bad luck with EH with only 1 dark UR and 1 dark SR but really want the LR. I have a few Cranky Relena ATK and DEF 250% up. Also have ~2k jewels. Is it wise to use them this event to buy 20+ keys for EH? Since I only get 1-2 coins it's really hard to hit the right panel... :( Or save since I have a good superbuffer already? Thank you in advance for advice :)
