I played the same army again and did exactly this. I walked between worlds my temple guard unit in front of his 40 strong unit of spear men then buffed them with Wisson’s. I was charged by them and by a unit of high elf cavalry in the flank. They managed to kill 6 temple guard. When I hit back there was a dead champion (2 wounds + overkill), 2 dead cavalry and 9 dead spear men. I won the combat and managed to overrun his spear men when they fled. This did leave me open to a flank charge from the Phoenix guard but at this point the game was over for the high elves. My unit of 35 regular saurus hadn’t received a scratch by this point and was closing in. The deployment phase won me this game.
