So I got that shiny amoongus from mystery gift in shield, and it came with a focus sash. It’s a defensive mon, so idk if a focus sash would be all that good, and I don’t know if I should leave it be or replace the focus sash with leftovers. The moveset, EVs, and nature are the same as it came with, I didn’t change anything. What should I do?
I believe that focus sash is used on amoonguss to ensure that it gets a spore off even after max airstream, one of the best moves in doubles and very common on Pokemon like dragapult, cinderace and togekiss. Black sludge is much better for singles, but in VGC (in which the event Amoonguss was actually used in a tournament) focus sash and coba berry (flying resist) are actually very common. According to Pikalytics, Coba Berry is the most common with 1/3 of people using it, and 1/4 of people are using focus sash.
The short answer is, focus sash is a good item that can be interchanged with a coba berry in VGC, but leftovers/black sludge is better in singles.
Hope I helped!
I think instead you should use a Pokemon with trick room and teleport like Xatu, and the status moves your opponent will use will be bounced off or stealth rock and sticky web or spikes, so use trick room first, then use teleport to Amoonguss and use spore then start to set up with Amoonguss, That, my friend, is my opinion and I ever used this strategy and won a couple of times.

Heat Wave to eliminate all Bug Types and powerful Flying Types like Corviknight and Skarmory that could really prove a threat to Amoonguss and Psychic for the STAB move. Trick Room to set up on the first turn or maybe after done eliminating or weakening any threats against Amoonguss, then Teleport to bring Amoonguss in safely. Magic Bounce to give Sticky Webbers or status Pokemon bad karma.
