"In honor of our fathers" - "One Khan, One Clan" [Campaign 3, Mission 2]

Help me, I've amassed an army of 250 Warlocks, 300 Goblin Wolves, 126 upgraded Centaurs, 64 Dryads, 33 Wolf Riders, and 8 Griffins. I'm facing a brown-colored player, and I feel like my army isn't strong enough. What should I do? I'm playing on Recruit difficulty:smile45: :smile45:
