I'm afraid we're getting 3 hit type girls in a row next. Then 2 pierce girls, then a magic, then another pierce and another hit, and then we'll get a slice girl again.
Re-issue events look very similar to that: it will be a while before we see a Slice girl again.
So, I guess you won't need too many red dragons for a while. And can now level your slice girls to 70.
