Morty tokens

When you get the Morty tokens, should I spend them, or "trade" them as soon as I get them? Or should I save them? Do you get better Mortys if you spend multiple tokens vs spending one at a time?
Please help. I couldn't find anything anywhere on this topic.
Thank you!!

If you are talking about the Tokens you win in the Morty games, you win a total of 5, and you turn them in for 1 Morty each : Mortys 138-142; Headism Morty, Turbulent Juice Morty, Jerry Fan Morty, Exoskeleton Morty, and Sexy Devil Morty. (If I'm remembering this right, at least.) You can turn them in anytime, last time I didn't bother because it was easier to keep the Tokens in the Items section, than it was to turn them in and have to make room in the very crowded Morty Daycare.

Hope this helps.
