I want to share this team first because I like it but also because I think that the Incineroar/Victini combination is a really good combo in terms of supporting setting up trick room. Basically, because of psychic terrain, fake out is no longer the dynamite support option that it used to be. Incineroar provides the fairly standard fake out support for trick room. Since victini can reliably outspeed even scarf lele, final gambit lets you reliably get trick room up in the face of psychic terrain teams. Having built around trick room a fair bit, scarf final gambit is the best non fake out option since it allows you to still build the most complete team in my opinion. Redirection isnt as great because amoongus would require tapu bulu, which is tough to build around defensively, and all of the follow me options frankly suck. Ally switch simply isn't reliable enough and requires guessing. While you do end up with double fires, the hyper offense/suicide bombing nature of victini makes this less of an issue, especially compared to amonguss, who requires the better defensive synergy in order to be able to pivot effectively.
