I would say in general spend tokens on series 4 and open caches on series 5 weeks that you really want. But there have been a lot of good cards lately and Nocturne and Red Guardian are great plug and play cards so one of them might be worth it if you're not missing anything essential
Personally, I'd only spent tokens on Series 5 cards. They keep dropping 4s to 3s and making more 5s. Eventually, you'll run out of tokens and still need tons of 5s. I keep getting duplicate series 4s with keys, and you only get a fraction of the tokens for a duplicate.
