Edge Miles is reward currency of Atlas card. You get different conversion ratios as compared to Magnus' edge rewards and you cant merge them both.
You can however, transfer to same partners. Different ratios though as I mentioned.
But isnt this Credit Card FOMO at the highest. Almost all premium cards do this / used to do this. DCB, SCU etc.
Even Ultra Premium lifestyle cards such as Amex Plat in US make up for the fees with various vouchers etc.
Nothing wrong with paid cards, I myself have many.
TL;DR:
Banks ko ideas...
Yeah, its not something that everyone gets apparently. Guess the 4.8% figure going around is causing this.
Its equivalent to the times when everyone thought all loyalty points have equal value.
