Yes, the Conflux doesn't give Necromancers an easy time. A more specific tip: upgrade the butterflies immediately. Use their retaliatory attack to quickly capture nearby mines and resources. Upgrade to the second or third tier as quickly as possible, focusing on archers. After that, clear out the entire surrounding area. Then, develop as quickly as possible to get phoenixes and pawns. If you haven't secured land and air dominance by this point, build a university and acquire those skills.
