I didn't see anyone post this, but apparently sometime within the past few months, Sad Littles did a 3 card promo set exclusive to the Project Comic Con, a show in St.Louis, MO.

It has been posted elsewhere that Sad Littles is sending the PCCEP3 card of Femforce to people for a SASE

I have finally seen the other 2 cards from this set. PCCEP1 is Aegis (Legacies End) and PCCEP2 is Radu (Dreamers of Darkness)
