I apologize if you took offense to my post. I just don't initially view Castellan of the Rock vs Long Lances in the same manner that you do. Please don't refrain from posting what you think because it's a valuable and fun discussion.
Thanks for the insightful post!
I forgot about the non-attachment requirement for Castellan.
I am removing "Limited Response" from Castellan and turning it into "Limit 1 per phase" for the purposes of this fun debate. It will never become an limitless response.
You outlined why Long Lances is far more versatile than Castellan. However, I think that it is safe to say that they are generally uncomparable because of how they are used. It's more of a control card versus a rush or utility multiplier card.
Long Lances increases your ability to perform actions for you in a game.
-Allows you to reuse your own characters for challenges and paying for costs. These characters are limited to Targaryen characters only.
-Generally easy to trigger with the number of put into play effects Targaryen has.
Castellan deceases your opponents ability to do perform certain actions in a game.
-Allows you to restrict the opponents ability to use targeted characters that may be effective in challenges or for paying for costs. These characters can be any opponents character that has no attachments.
-Very easy to trigger by playing a character or location.
Castellan disables characters that don't kneel to attack/defend, kneel to trigger their abilities, and helps keep big and key characters from being effective during the challenge phase. To overcome what Castellan does, you need to have a better board position after the kneeling, a restanding ability, or really good characters still standing afterward.
Long Lances enables your own characters to allow them to be used multiple times in a round/phase. These characters might be key targaryen characters in the game and can help you win multiple challenges.
The question is, what is easier to overcome? Is it easier to deal with having a key character degenerated board position? Or is it easier to overcome characters that have been restood and are ready to use their ability or reused in a different challenge? The point of view of the opponent will mostly come from what happens in the Challenge phase as this is where the board position battle rears its ugly head the most.
