Last ones I bought was when they did the 4-colour commanders, but since my EDH friends have now moved to playing only in proxies so I never buy any cards these days.
Well, even more absurdly, I buy all these, but I barely get to play Legacy once a month, and then I play EDH less than once every 3-4 months.
I'm addicted to collecting though...but with the prices on those 2016 ones, likely I never get them to have "all" of them.
