The reveals don't really keep up with the Limited Rgatchas egatcha/revivalgatcha/srgatcha that we are getting now a days.
Just from the event there's 5 Reveals from ep rewards and 3 more if your in the top 1k for rank and support. And there are 5 tickets that we get that require a reveal (1event/3revival/1sr from 14th day). So with the new Rgatcha Sr's you can break even if your stupid lucky but that's about it.
Personally I'm down to 94 reveals and I had 150+ before the Halloween limited rgatchas.
