My guess is that they are referring to a complete holofoil set, which would be the 62 base cards and the 11 holofoil MR cards.
If that is what you are asking them no, I don't think anyone has completed that yet, still a couple of the MR holofoils still to be found, that we know of
From my spreadsheet, there have been 68 of the 73 Holofoil cards found
We are still looking for MR3, MR4A, MR6, MR6A, and MR7A
All 72 Crystal Sparkle have been found. It is confirmed there is no MR8 Crystal Sparkle
Thanks for the pictures everyone.. seemingly so far we have already seen 29 of the 62 Diamond Refractors!
