Casual Dueling games

Colleagues!Please tell me such free-play online games that would be:

— based on synchronous dueling mechanics;

— made in cartoon technique and would appeal to a wide audience.
A small comment: for example, the Legend: The Legacy of Dragons — it is made on the basis of duels, but about magmars, elementals and other obscenities that disgust many; A cheerful farmer is cute and funny, but without duels.

Are there any successful games that would combine synchronous “combat” sessions and casual submission?Maybroots and football managers are almost suitable, but there fights, as I understand it, occur without player intervention and are asynchronous.

Surely there must be some Pokemon arenas and others like them, which both children and housewives can play, but which resemble “classic” Russian browsers in terms of social infrastructure and monetization mechanics?
