Here's some ideas for replacements I had:
as a replacement for Victant.
Like Victant, Golmanitan is a physical Fire type with high attack and an arguably better typing. Unlike Victant it is slower and can't really hold any items to remedy this due to its ability only granting a boost at the expense of his held item's effect.
as a replacement for Mienzy.
While Komodreigon is functionally very different from Mienzy, it still serves the role of Dragon/Fighting type on top of decent bulk, while not entirely negating stall at the same time.
as a replacement for either Chazma or Snorligatr.
Parasol would be a great bulky offensive force. As the only Bug/Steel with an immunity to fire moves, it would be able to tank hits while dishing out high damage thanks to its attack stat.
