@Scarecrow and @Sernarok
Glad to see it was sorted out 
Do note too that the special skill description for both Mitsuko and Ursena cards were updated to say “and blocks negative effects”
Card as of V25 for Mitsuko for e.g.
Dispelling is included as a negative effect – aside Snow White, also means that Sonya and Frida can’t dispel either
