I don't understand how anyone can consider the Tower a weak castle, given the pool of templates available now. A Tower with a Bibliophile on top is stronger than almost half of the castles – if you know how to build it.
Could you elaborate on which templates you're referring to? And which castles? Just based on my experience, even on a low-mana map, even against Swamp, Inferno, or Citadel, during trading, I often end up selling the choice to my opponent, and I get the Tower with a positive mana regeneration (of course, the level of both me and my opponents isn't very high, but still...).
