Up to turn 115 I thought about surrendering to my opponent's mercy. Crag Hack without any land, 0 Dragon Fly Hives, 0 cons, the only external dwelling being orcs and a bunch of locusts. True, I had Boots and Gauntlets, so I didn't give up.
But then on turn 115 I simply find a Spirit of Oppression behind the locusts, an external dwelling of Roc with a native village, and right next to the Spirit of Oppression there's a double Mana.
On turn 122, with stats around 21 16 or thereabouts, Crag Hack without Oil hits GO with 86 locusts using only native troops, losing 3 goblins and 4 birds.
On his turn, the opponent surrenders.
Thanks for the game
