I had the same issue for a while, except I kept pulling Myst and Wrestler X. Did get one Toad early on. Then pulled a bunch of Tomb and Glooms. Last night I finally got a Ms. Trial, but the game just doesn’t want me having Wildcard!
Tasia, Necrobreaker isn't in the loot table. It's only specially awarded at events, and one time awarded for the top winners of the Halloween PF.
