Answer 3

Gen 9 NU HO Lead

Jolly Nature
- Spikes
- Rapid Spin
- Poltergeist
- Curse

If you feel like using an Brambleghast as an HO lead in NU, here you go. Brambleghast is nice as a HO lead in NU due to its Ghost typing letting it spinblock opposing leads, and utility in Spikes and Curse to help the breakers and sweepers on your team. Spikes lets Brambleghast set a hazard that chips grounded Pokemon to weaken them for Brambleghast's teammates. Rapid Spin allows Brambleghast to spin away any hazards on its side. Poltergeist is used for a powerful Ghost STAB that is useful to chip opposing Pokemon. Curse is used to allow Brambleghast to force chip on opposing Pokemon at the cost of losing HP, with the Curse chip giving an opportunity for a Pokemon on your team to setup and break down a team. Focus Sash is used to guarantee Brambleghast can setup a Spike. You aren't really going to want to Tera with Brambleghast, but Fairy can be used to resist Dark moves... Or you could just have Ghost as the Tera Type and don't use your Tera on Brambleghast.
