All Decades Mystery Game Please!

Now that we have a few thousand mystery cards, can we please have a game that has all 4 decades in it, sorta like ATG? ATM maybe...

Think of the possibilities!

I would sign up for something like that in a second. Would be tons of fun.

Good idea, but might require work from SoM. Does Blyleven get his 70's, 80's or 90's card or does he get a new card made up using some of the years from those cards, or entirely new ones? Is Reggie the fast mobile Reggie of the 70's or the plodding slugger of the 80's, or somewhere in between?
