Bought enough quartz to blend with maintenance for another 10-roll. Picked up a Marie and a Heracles spook, so not completely empty-handed. Looks like MHX really doesn't want to meet the darthzerker.
On another note, among 5-star zerkers, we have quite the family. Brotoki, Mama Raikou, Uncle Vlad, Edgy teen Cu Alter, Nanny Nightingale, and now Imouto X.
