Can you gain priority during a Hold step (after readying runes from Annie's ability) to use an action like Gust before the opponent scores?

Ruling: No, you cannot normally gain priority during a Hold step to use the runes readied by Annie's ability before scoring occurs. Once Annie's trigger resolves, you cannot use actions during that step.

Nuances:

• You could use Gust earlier during your turn before passing, but this would require not spending all your energy
• If you have another end phase trigger (like Targon's Peak, Temporary, or Jinx), you can gain priority between trigger resolutions and use Gust at that point with the readied runes from Annie
