Tactics for Necropolis.

I'm interested in an expert-level strategy for the "L" map. The restriction is no diplomacy. Here's my thinking: if you see that you have enough gold and resources (either lying around or available to take from others), build Vampires and a Castle, buy everything you can, and go destroy everything. Build up your troops and accumulate gold. If there's not much to destroy and the easy pickings are gone, focus on building up your army with gold. If you don't have gold or resources, you've lost. Because you can build Vampires, but without a Castle, and while you're building a Town Hall and buying troops and getting your economy going, it'll be week 3 at best, and then you'll try to scrape together an army, but you'll probably get crushed if your opponent isn't completely terrible. +1 question: on whom should I focus on building skeletons? Sometimes there are 20-49 units of levels 3, 4, 5, and 6, and that's it. 500 skeletons don't scare anyone. But if there are only 1 or 2, then it's all good. I mainly play as the Hive. A Warrior with a Mage bonus. Skills: Magic Logistics Attack Defense Tactics Magic, Earth: Shield, Slow, Stone Skin. Air: Portal, Haste. Wisdom. Sometimes it doesn't work out, and you have to choose between Navigation, Mysticism, or other less useful skills. If you have the spells Teleport and Berserk, that's awesome. Another downside is that you mostly have to move aggressively, but half of your units are slow, which is bad. If the enemy only has ranged units (that can actually do something), it's better to Blind them (which is really great) and wait for them. This is just my opinion; I'll be happy to be corrected if I'm wrong. Also, I'm self-taught
