When will festival dancer be back on leg banner?

Hmm. It depends. We just got a Brave Hector and it's been less than a month, so if you're lucky, even December.

Can't be a "leg banner" without Nephenee.

I'd anticipate January / February.

The current banner has finished the first wave of this year's Summer units, so next month should give 3 of the next wave, assuming IS sticks to the trend of giving 3 seasonals per banner. Then, the Jan / Feb banner should be one Summer and two Festival units.
