If Dazzling Aurora's end of turn effect flips Deadbloom Predator and you conquer Targon's Peak during the resulting showdown, can you ready 2 runes from Targon's Peak's ability?

Ruling: No, you cannot ready 2 runes. While Targon's Peak does trigger when conquered, the "at the end of this turn" condition has already passed, so the rune readying effect does not occur.

Sequence:

• At the start of the Ending Step (517.1), all "at the end of turn" triggers occur simultaneously, including Dazzling Aurora
• Aurora's trigger resolves, flipping Deadbloom Predator
• Deadbloom wins the showdown and you conquer Targon's Peak
• Targon's Peak's conquer trigger checks for "at the end of this turn" but that event has already occurred
• The runes do not ready because the Ending Step trigger moment has passed

Nuances:

• "At the end of your/this turn" refers to a specific moment (the start of the Ending Step), not an ongoing condition throughout the End Phase
• Triggers only activate for cards present at the moment the triggering event occurs
• If you conquer Targon's Peak on your opponent's turn, you would ready runes at the end of their turn ("this turn" refers to the current turn when triggered)
