Can Nocturne be played through look AND reveal or look only and no reveal?

Nocturne can be played through both looking at and revealing it from the top of your deck.

According to the card's text and established rulings:

• Card Text: "As you look at or reveal me from the top of your deck, you may banish me. If you do, you may play me for [A]."
• Ruling: Nocturne's ability triggers when it is either looked at or revealed from the top of your deck. While "looking at" and "revealing" are technically different game actions (as defined in Rule 424), Nocturne's ability explicitly functions for both.

Important Nuances:

• Draw for Turn: You cannot play Nocturne for [A] when you draw it for your turn. The effect must be triggered by an ability or spell that specifically "looks at" or "reveals" the top card(s) of your deck (e.g., Stacked Deck or Vision effects).
• Errata/FAQ: This interaction is confirmed by multiple RiftJudge FAQs (e.g., FAQ #1433, #2368, #4347), which clarify that both mechanics trigger the ability.
