Anyone know if you do a Draft Player set if the player still comes from a pack?

Has to be someone out there whose done one of these sets since the first round of the draft ended and can tell me if it says Pack opening or Set completion reward on the back?

If you did the set prior to the player being drafted you got a collectible that turned into a pack once the player was drafted so the card would say Source: Pack opening. Does anyone know if you do the set now if it says Source: Set completion reward instead?

EDIT: Asking because I like my cards to say Source: Pack opening if possible. Lol.
