However, for me, the topic of this thread is relevant in this context: when capturing a castle, will I buy a small number of level 7 creatures there (around 3), or will I spend resources and gold on upgrades?
Archangels, in my opinion, look better than all the others. Phoenixes are also good (considering their quantity). I take Black Dragons if I expect battles with a powerful mage.
