New card type

[Locutus]

Given the large amount of Fortress destruction now available, I have thought of a new class of card that could mitigate this:  Gates/Walls/Defensive Works.  Territory class.  May be placed on a fortress to act as a protect (not unlike what Glory of the Lord does for Solomon's Temple).
Reprint such cards as Gates of Samaria and Gates of Jerusalem.  Many sites and Fortresses would lend themselves to this type of card construct.
Thoughts?

That's a cool concept! I like it! However, I think the game is trying to move away from protection being strong/reliable.

How does it function differently than fortresses other than not being targeted by cards that target fortresses?

[Locutus]

A gate or defensive work would provide protection for that fortress, so that a card like Shipwreck or Assyrian Siege Army couldn’t harm the fortress.

Psh, that's what this card is for...

On a more serious note, it's a decent idea, but I'm not sure it necessarily merits a new card type. There may not be many, but there are a few cards that protect Fortresses already and if Fortress destruction seems to be an issue later on then I'm sure there will be cards similar to the one above printed with more user-friendly abilities.
