An uncontested speed tier alongside CB Tera Fighting Close Combat makes Pheromosa a better wallbreaker than in prior generations. It's still fairly niche due to Tera dependancy, but it's a much more self-sufficient option than before nonetheless. Dragon Dance Dragonium Z Zekrom is a legitimate threat on hyper offense, capable of breaking through even traditional checks like Arceus-Ground / Primal Groudon after some chip. Arceus-Rock is mostly useful for the Flying-resistance, letting it sit on Ho-Oh, Mega Salamence, Rayquaza etc. but it faces heavy competition from other Arceus formes that match up better into more relevant metagame threats. Roaring Moon is a very niche Dragon Dance Terastal sweeper on hyper offense that doesn't take up the Mega / Arceus slot, although I haven't used this Pokemon at all so I can't speak more on it.
I'll go over the sample sets and see if there are any more inconsistencies, thanks for notifying
