Tactics for Rampart.

Anophele, typically by the second week, you need to gather all the best stuff from the spawn - Hives, Griffin Conservatories, and move to the treasure zone. There, fill your stack with ducks, already take Dragon Utopias, etc. And building dragons is indeed rare. If their external dwelling is there, that's a different matter. Because unupgraded ones are garbage, while upgraded ones are expensive. And unlike angels from the conservatories, there's nothing to reinforce their stack with.
