OG vs Ad Finem
Perhaps the most famous twist ending in the history of Dota 2, this match was being hailed as a classic even before its conclusion. By December 2016, OG had firmly established itself as one of the world's premier organizations. Ad Finem, by contrast, was in the midst of its own Cinderella story. Over the last calendar year, Ad Finem had improbably emerged out of Greece to become one of Europe's best teams. In a scene dominated by its old guard, the arrival of five Greeks bearing prodigious gifts into professional Dota 2 shook the foundations of the scene. En route to the grand finals, Ad Finem eliminated two Chinese teams, Newbee and LGD.Young, and The International 16 runners-up, Digital Chaos.
After losing the first two games of the grand finals against OG, Ad Finem looked sunk. But the team somehow recaptured whatever had been missing in games one and two, setting the stage for an explosive match – the game is maximalist in every sense of the word. At 78 minutes, it was the Boston Major's longest and most explosive match, featuring over 100 kills, a backup Divine Rapier (an high risk, high reward damage item that drops on death), and multiple late game lead swings. Though OG went on to win The Boston Major, their cataclysmic game against Ad Finem declared that the Greek upstarts were here to stay.
