More than 21 new cards will be added to the second Gasha from 12:2 on the 50st. When I tried 10 consecutive trials, I got it just fine, and the result is that I got ridiculous feeling that only one new card was acquired.
Once you've finished adding the Yoshi Card database, try again...
It is a really bad specification that the second bullet contains the first bullet. UR came, but it was the first.
