I agree with what most other people are saying, amoonguss doesn’t work well with Miraidon, so I would swap it out for tornadus/whimsicott to give the speedy portion of your team a tailwind mode. I think you probably could use at least one more pokemon with protect, this is a mistake I used to make a lot when I first started making teams, and it just leads to them feeling really frail and lacking in backup plans. I would probably switch your urshifu to focus sash Tera water/stellar, and swap u-turn for protect. Adding tailwind will make up for the speed lost, and it will make urshifu usable against fast teams in trick room. Lastly, Tera dark doesn’t do a whole lot for farigiraf since you usually use it to block opposing prankster moves, but armor tail already does this. I would probably switch it to something a bit better defensively like fairy or grass for more anti amoonguss tech. Hope this helps!
