Personally I wouldn't they are like the red gourd where they mostly roll with purple and some gold stats. Also the chances of it dropping something other than the gourd seem to be low as I had to open 5 boxes before I got the reaper mask. There is better things to spend your hard earned coupons on such as cave key packs, refines and lucky board. when we get the new TI these will be obtainable anyway (and with better stats probably).

not worth spending on tbh

Don't spend on it! You will be able to obtain them in the future (for FREE), and it's a horribly expensive way to get cheaped out.

Like others said before. It's a waste of coupons and you will get them for free in the 32k TI anyway. Just be patient and don't buy them :-)
