When can an on-deck ability, such as Celenia's, be used?
Two replies in one thread describe on-deck abilities this way, and the rulebook does not cover the timing.

Whenever the card is your on-deck card, at any point in the turn, including before you push or during Harvest. No last-flip timing applies.
