Marvel Machine is Back! 6/6 – 6/12

Does the Scarlet Ring still act as a joker for the gollux set even if you have the actual gollux ring?
i.e. Does this work? Gollux Ring, Pendant, Pendant/Earring, Scarlet Ring

Also do joker items also act as jokers for 2 sets simultaneously? i.e. Can you activate the Kritias Effect(I know this hasn't come yet to GMS) and Gollux effect?

If so... these two accessories seem very valuable :x
