While it's true you CAN have more than one Power+ treasure and with enough you can churn out quite a nice amount each day, when it comes to crystals they are incredibly rare for one reason.

If people could stock up on crystal Power+ treasures and have enough where you could produce a lot of crystals each day, DevSisters wouldn't have much, or any, income at all. That is why they intentionally made the crystal Power+ treasures have really low chances of triggering AND incredibly rare so people will actually buy from them if they need crystals.

It is entirely possible to have such a "Crystal Engine" except it would either require tremendous luck or thousands of dollars.

Heck, I'm level 36 in Cookie Run and I only have TWO crystal Power+ treasures (soon to be 3 as soon as I max out Prophet Cookie).
