Quite funny mistake from the corp in that game. Would have lost the game without Punitive Counterstrike in hand by calculating the combo wrong. I guess the turn went like 1. Power Shutdown, use Jackson, 2. Diagnostic combo but play 0 of the revealed cards, 3 Punitive Counterstrike. He did actually play the SEA source for 2 credits off the Diagnostics. But yeah, corp almost punted that game.
