Where in the fuck is Zombie Marguerite?

I haven't seen her in the shop at all this time. Barely got her at lvl 3. Each week I've only managed to get her lvl 5. Never get the cards for lvl 6. A couple are stuck in with the customer bonuses but Im usually buying a whole level of cards for her. Apparently you guys won't let me do that this time, what the shit?
