Hello Everyone!
Sadly, Modern Masters was a very limited set and despite our best efforts, we have not been able to source them in any meaningful quantity.
Maybe someday in the future we'll come upon a chest full of Modern Masters boxes we can list but that day is not today.
Thanks for your votes and patience! We'll keep this in mind and do our best to list them if the opportunity should ever arise.
Just a quick update - as you guys know, this was a limited run set which is no longer available from most vendors (at least not at a decent price). We can look into running them, but right now market price for the boxes are about $250-$260.. Will post more updates if we have any new info.
