Me: Why is everybody so freaking short on Miracle Crystals??? I have like... 400 just sitting around??
Also me: Remembers I play more Free Live than MultiLive, have a tight-ass scouting-schedule, as of 30/6, I have done 4 scouts in total, I have gotten INSANELY lucky with Crystal Drops in Veteran Rooms and have very few cards and gain cards even slower
Me, after thinking for like 2 seconds: OK I UNDERSTAND NOW.
(Sending some crystal luck to y'all short on them!!)
Edit: Somebody in the comments mentioned that you can grind for MCs in Regular Rooms should you ever need it!!
