Some things.
Toxapex should be remained "KingPex" because it's more appropriate.
I think the Defensive Heatran and Offensive Z-Crystal should be switched around. Also are we considering Utility the Sub set to? Magma Storm, Toxic, Sub, Taunt / Earth Power. Utility is a bit weird in wording here.
Sub Mawile should be a set. I would put it at A-.
CB Bulu should be above Sub SD. I think its just a better set in general and Tapu Bulu needs as much coverage as possible anyways for certain checks, something that I can think the Sub set fails to accomplish. The SubSD set is stronger on Kartana anyways.
Scarf Chomp to C. Hard to justify Chomp on a team already over something like Lando-T and better scarfers to use.
The utility set should be above Calm Mind on M-Latias and perhaps even put CM at B. I don't think the CM set is very effective and I know people like to hype it up but the vulnerability it has to Band Tar, Toxic, Magearna, and over-reliance on coverage I find makes the set very specific for certain builds / risky as your win condition. The utility in defog has similar issues but you get a reliable defogger that doesn't care about Toxic Spikes and Spikes, Lando-T, can't be trapped by Magnezone, and isn't Rock Weak all at once. These are some common issues that plague all the viable defoggers in terms of their effectiveness in removing hazards. It's more about which roles I feel M-Latias functions better with.
Hawlucha I would just name SD. I'm seeing more builds utilize other Tapus with it to activate Unburden and the corresponding seed.
