Depends, is the deck a positive deck or a negative deck? I say that because there were so many celebrity deaths in 2016, then you had a heck of a lot of political wars going on in the middle east, there was also Brexit which was huge. But if it's just concentrating on the biggest story of the year, then it'd have to be election.
Although, I wouldn't mind seeing a deck with the celebs we've lost this year. Muhammad Ali, David Bowie, Prince, Alan Rickman, Lemmy, Gary Shandling, Gene Wilder, Arnold Palmer.. I suppose Fidel Castro can be added now (although not really a celeb)
