If a player plays oasis respite targeting a invoke dragon card on the layer (that's say it's a themai to make make the most sense). Would it prevent the damage from the invoked dragon once it's on the arena?

9.1.2c If an effect applies to a double-sided card, it continues to apply to the card even if its properties are defined by a different face, as long as it does not cease to exist between changing properties.
Example: Oasis Respite has the text “Prevent the next 4 damage that would be dealt to target hero this turn by a source of your choice.”. If a standard double-faced card with its front-face active, is chosen as the source, and then that card resolves, enters the arena, and its back-face becomes active, it is still subjected to Oasis Respite’s effect.
Yes it will prevent the damage
