Gold foils are reasonable right now. I wonder if thats because the first who receive GF are those who dont want them, they slowly sell for reasonable prices (6-7x of RF) and then the real diamond hands hold forever, and you nevcer get it for less than 50X. Starting to think so anyways.
Rentals on Rebellion and even RW is pretty amazing tho as well, another angle to consider if you're worried about paying too much for packs. Rentals make up for some of that.
