My main concern is how this fits into the promo card schedule.

As previously mentioned in a town hall by Aggy, we finally settled into a system of 4 promo cards a year (around one per 3 months on average). If there is enough space to fit this in as one of the 4 promo cards, then maybe that is okay. But if Yabapmatt/Aggy already have plans for the 4 promo cards this year, then I don't know if the company will have the bandwidth to do this as well.
