Any others in the clutch look like they picked up Trick? Should be roughly 50/50 split. I think there is a good possibility but I wouldn't say definitively. I don't know near enough about OG to understand entirely how that would interact with Black Pastel, which already can have highly variable back patterning. From glancing on MM, all the OG Black Pastel have a strong orange in dorsal patterning, and the few I see with the Trick-like donuts in the dorsal have only one or two. If I were personally selling, I'd list it as "probable Trick" and include some background info in the body of the listing. It may be a world first, in which case I would keep it and work on proving it out.
