Mixi is apologizing for the way the Co-Op Lottery event was executed and causing disappointment to many strikers. They will be re-evaluating the event and have something ready to announce around Jun 23 (next week)
We'll see what they announce soon then.
Essentially meaning, if you lottery for Zodiac you're guaranteed to get it now.
You actually do have an incentive to try for the limited monsters that are in the gacha!
The lineup for the lottery has also been tweaked. The weird non-limited mons removed for some older classics
The Co-Op Lottery event will be kicked off one more time on Jun 24.
Make sure to get your current results by Jun 22 3:59.
The biggest change to the 2nd attempt of the Co-Op Lottery event is that there will now be 100M copies of Zodiac available (updated from 600k).
