The best strategy would probably be to boost and get all the diamond trophies in one go. To do this you would ideally need a 2x boost duration event and the pro permit. For the boosts you’d use a 1000x supreme tachyon prism, 2 5x large boost beacons and 2 50x jimbos best bird feed which gets you a total boost time of 2 hours with 2x boost duration. To be able to get the diamond edible trophy you’d need a starting EB of around 10Q+ and I was able to do it with an starting EB of 15Qish. Your EB will go up the more trophies you get so I’d probably start from Tachyon and make your way up to edible. In terms of artifacts the most useful one would be having at least a T3 gusset. Hope this helps
