When Dazzling Aurora reveals all cards from the Main Deck without finding a unit, what happens? Does this trigger a Burn Out?

Ruling: You do as much as you can. Since no unit was found, you recycle all the revealed cards and continue the game. This does not trigger a Burn Out because revealed cards never leave the Main Deck zone - they remain in the Main Deck even while revealed.

Sequence:

• Reveal cards from the top of your Main Deck until you reveal a unit or run out of cards
• If no unit is found after revealing all cards, the instruction completes as much as possible
• Recycle all revealed cards
• Continue the game

Nuances:

• A Burn Out only occurs if you attempt to draw or reveal from an already empty Main Deck (0 cards before starting the action)
• Revealed cards are still considered to be in the Main Deck zone, so the deck is never empty during the reveal process
• This same principle applies to other reveal effects (like Teemo revealing 5 cards when only 3 remain)
• Draw effects work differently - attempting to draw more cards than available will trigger a Burn Out
