I would say go for the standard bundle (1 legendary 10 packs) cause that's 2 guaranteed legendaries, and since he was gone for 2 years, remember that the new pity timer for unopened sets is 10 packs, so maybe try to mix them up (10 sunken city packs, 10 stormwind packs etc). That way he will at least have enough dust to make some decks. Maybe he'll even get lucky and get the shaman quest, which is kinda viable in wild right now.
