If I conquer Zaun Warrens while having 0 cards in hand and a Rocket in my trash, can I draw from Warrens and then discard the card I drew to get Rocket back?

Ruling: Yes, you can draw from Zaun Warrens and then discard that card to return Rocket from trash.

Sequence:

• Order the triggers with Rocket above Zaun Warrens on the stack
• Zaun Warrens resolves first: you can't discard (empty hand), then you draw 1 card
• Rocket trigger resolves: you can now discard the card you just drew to return Rocket to hand
