Does revealing a card with Apprentice Smith count for the purpose of triggering Nocturne?

Question

Accepted Answer

I can't be 100% certain because Nocturne's exact text wasn't provided. Based on the rules for Revealing, if Nocturne triggers on a card being Revealed (from any zone) then the reveal performed by Apprentice Smith does qualify and would trigger Nocturne. If Nocturne requires a reveal from a specific zone (for example, "when a card in hand is revealed") or has additional restrictions, the Apprentice Smith reveal may not qualify.

Yes — assuming Nocturne's trigger is simply "when a card is revealed" (with no zone restriction), the reveal caused by Apprentice Smith counts as that reveal and would trigger Nocturne. The reveal is an actual Reveal action of the top card of your Main Deck instructed by a game effect and is therefore the kind of event that other effects watching for Reveals would see [424] [424.3] [424.2.a].

Apprentice Smith's triggered ability resolves and instructs you to Reveal the top card of your Main Deck. This is a Reveal action executed as written [424] [424.3]. That top card is presented to all players (it remains in the Main Deck while revealed) so the reveal exists as game information other effects can reference [424] [424.1.a.2]. Any effect that watches for cards being Revealed should see this Reveal and trigger, unless its text imposes specific restrictions (zone, controller, card type, etc.) that do not match this Reveal [424] [424.2.a].

If Nocturne only triggers on reveals from a specific zone (for example, "when a card in hand is revealed"), the Apprentice Smith reveal from the top of the Main Deck would not match. If Nocturne's trigger includes controller restrictions (for example, "when an opponent reveals a card"), you must compare the controller specified by Nocturne to the controller doing the reveal via Apprentice Smith. If Nocturne's trigger requires the revealed card to be a specific card type or have some property that the revealed card does not have, the trigger would not occur even though a Reveal happened. If the deck is empty and the reveal would be in excess of the number of cards in the deck, refer to Burn Out rules; reveals in excess are handled specially and could change whether the reveal (and thus any triggered effect) occurs [431.1.c].

The key point is that Apprentice Smith's text instructs you to "reveal the top card of your Main Deck." That instruction is exactly a Reveal action as defined by the rules: Revealing presents a card from a zone to all players as temporary information and is a Limited Action [424] [424.3]. When you carry out that Reveal, the revealed card remains in the Main Deck while revealed and other cards and effects can reference that act of being Revealed [424] [424.1.a.2]. Therefore, any other effect that triggers when a card is Revealed should detect the Reveal created by Apprentice Smith and trigger, provided the trigger's conditions match (no zone/controller/type restrictions that would exclude this Reveal) [424] [424.2.a]. Because I don't have the literal text of Nocturne, I can't say with absolute certainty whether its trigger has extra requirements (zone, controller, or card-type constraints). If Nocturne is simply "When a card is revealed," then the Smith reveal qualifies; if Nocturne says "when a card in hand is revealed" or similar, the Smith reveal would not match. Those are the relevant distinctions to check on Nocturne's wording.
