Is Razor of the Dawn Castle a Castle?
No, it doesn't have the Castle keyword and the word "Castle" in its title isn't enough to make that card a Castle.
Referring to things: "Likewise, text that asks for a single word is not satisfied by a multi-word keyword or title that contains that word. For instance, text that asks for a “Battle ability” is not satisfied by a Reaction ability on a Battle Maiden, nor is text that asks for a Temple satisfied by the keyword or title “Temple Guardian”."
Card title: "A card’s title does not give it any traits or keywords, although some of its keywords may duplicate descriptive terms in the title. Example: A card titled “Keeper of the Temples” would not be considered a Temple card unless it had the Temple keyword in its textbox."

Even if Razor of the Dawn Castle had the Castle keyword, Strongholds are not Holdings.
