Hey there, followers! While I do answer work questions on this account, it is still my personal twitter account. I will aggressively block people who are rude to others in my mentions, so please be nice!
@ScottHevel It will lose the ability, so you can’t activate it. However, if you’ve already activated it before Blood Moon entered, it will continue to use to be an artifact creature (in addition to being a Mountain land) until the effect ends at end of turn.
Blood Moon's effect turns Urza's Saga into a Mountain, and this causes it to lose all of its chapter abilities (but it keeps any granted abilities it has already gained) and has "T: Add {R}." It stays on the battlefield, but won't get a lore counter each turn.

@ScottHevel Blood Moon removes all other land subtypes and replaces them with Mountain. It doesn’t add the basic supertype or remove any existing card types (like artifact or creature) that it has. #WotCstaff
@t3dy From a strictly rules-oriented perspective, a granted ability is itself a thing, and there isn't any text attached to it. If a creature gains flying, it doesn't have the word "flying" printed on it, but it has an ability. #WotCstaff
@t3dy I think you've got the idea. Although, technically, it *is* a characteristic of the permanent on the battlefield, it's a different characteristic from its rules text.
@t3dy Sorry, I think I'm misunderstanding. Rules text and abilities are related but separate concepts. 109.3 lists them as separate kinds of characteristics. Similar to an effect changing a creature's power, an effect adding an ability doesn't change text on the card. #WotCstaff
@t3dy Those quotes are not from the rules mentioned, and appear to me to be completely made up. The rules you're looking for are 113.1a, which draws the clear distinction you're asking about, and 305.7, which explains that abilities from other effects won't be lost.

The FIN Release Notes (link in reply) announced that the Saga rules are changing a bit. This is solely for cases where a Saga somehow has zero chapter abilities. It won't be sacrificed immediately; it stays on the battlefield but stops getting lore counters each turn. #WotCstaff
@solysg Yes it is. The -1/-1 counters can’t be placed on your creature, so moving all the counters isn’t possible. The last ability offers The Ozolith offers a choice and, per the rule you mentioned, you can’t choose an option that’s illegal or impossible. #WotCstaff
@HanweirGarrison That ruling doesn’t really make sense to me and I believe it’s an error. I wouldn’t expect Hushbringer to prevent either Syr Konrad’s ability or our new Dragon friend’s ability from triggering. #WotCstaff
Saga creatures! Given a lot of underlying complexity, these were a spooky idea, and it was tempting to say "no, we can't do that." For rules, though, I'd rather say "Try that for a bit; let's see if it's fun. If it is, we'll figure out how it works." It turns out they're very fun
#MTGxFINALFANTASY “Summons” are Enchantment Creature Sagas, as seen here with Shiva from FINAL FANTASY X!
They allow you to utilize their powerful abilities before finishing in a blaze of glory with an ultimate ability.
