Kostya seems to have lost his touch... he could have resurrected a bunch of Archons in the first round, using a single Archon, giving him the first turn in the second round, then cast the second Implosion and buy out. A Papal exchange.
Actually, I was winning easily, but the morale of Yara's Vivams in two consecutive rounds ruined everything, especially in the most crucial rounds. What kind of exchange are you talking about?
