Question: is zacian or zamazenta better?
Answer: The Fairy/Steel type with Zacian is a great advantage over the Fighting/Steel of Zamazenta. Zamazenta has 3 weaknesses to worry about with Fire, Fighting, and Ground-type moves, while Zacian would only have to worry about two weaknesses Fire and Ground. ... This puts Zacian forward as a better Pokémon, battle wise.
