The weather setter of the team, I decided to go with something different from the usual set. I went physical. Ice shard means that abomasnow can revenge kill weakened threats, or flygon that are below 50%. Wood hammer does great damage due to its 120 bp, and recoil can allow it to safely get in a threat if aboma dies. Earthquake hits the steel and fire types that resist both moves. Icy rock also means that cetitan can continue its sweep for longer, as otherwise I find that effectively 2 turns to sweep (setting up hail, getting cetitan in and getting belly drum off) is not enough.
The second mon of the core, I decided to stick with mostly a standard set. The only change was making the tera type fire, which resists steel type moves but also makes it immune to burn, allowing cetitan to easily setup on incineroar.
Since we have three mons with a rocks weakness, we needed some hazard control. In comes HO mainstay cinccino. Standard set.
I wanted a spinblocker for the team, and chandelure is one of the best ghost types around. I decided to go with a special set. Usually on these niche HO teams, chandelure either goes with calm mind or memento. So what about both? Calm Mind means that chandelure can snowball into a threat quite quickly. However, if chandelure can't sweep, it can instead use memento to help a teammate sweep. I decided on colbur berry as the item, as you can take a knock off from the many mons that use it like incineroar, mienshao and toxicroak, and hit them back with an attack.
The designated defensive mon on the team, klefki can support the rest of the sweepers on the team. Standard set.
Finally, I wanted another abuser for veil, so in comes torterra. Torterra's main issue is that even after a boost, it can still be quite slow. With aurora veil, you can usually get two, which can end games on the spot potentially due to its immense power and speed. Standard set.
