Upcoming Mutants Should Have Horseman Synergies
I know that they added several Horseman synergies with existing champs when Apocalypse was released. No mutant since then has had a specific synergy when becoming a Horseman. I think that this should start being a part of the design process. Do not detract from the kit that you plan to design. Just add something a little extra and spicy. Would be cool if this wasn't just a thing of the past.
