Al C.risafulliI would say T206 (minus the big ones) is the main set where it's okay to consider it complete without some key cards. I don't know much about T210s, but I would think that might be another one. There are a few others, but like Scott says, not many.
I might be the only person on earth who thinks this, but I consider 1933 Goudey complete without the Lajoie, since it didn't come out in 1933.
Then again, I consider the 1934 Goudey set complete without the Lajoie, too.
Maybe I'd think differently if I were building a 1933 Goudey set.
Perhaps I'm just insane.
