how do you know they wont be using ranger keys at all? do you have some sort of inside information?

The guy who has real inside sources claimed that they are using keys.. and he's been right with his sources in the past... so I'm going to believe it's a possibility, but not a rumor.

saban is not used keys and they are used rangers cards

you keep saying that but how do you know whats coming NEXT year when we barely know whats this year

megaforce team used power cards in s1 and s2 insted of ranger keys

You could be right. Some signs point to you being right. However nothing is sure. What is surely true, is that there will be keys involved, either replacing cards or working alongside cards somehow. Or just for scenery. Who knows.
