It seems hopless for the Median because the ineluctable defection of the greeks. In the first game, the Persian crushed the opponent 5/1 in four turns.
So we decide with my opponent to switch side to see how long the Median can hold. And because bad luck for the Persian in cards (he had never the cards to activate the greeks, and no, the defection is not ineluctable) and dice (attacks totally ineffective the first two turns), the Median won 5/3 with a very agressive play.
So, even it's hopeless, you have to fight, and maybe the luck will decide of the fate of the battle.
