Elemental Inspiration also explicitly mentions 'random bonus effect'. Combining the fact this new card doesn't mention the word random with the fact these 8 Bandits have their own unique name and art makes me 95% sure there won't be duplicates per casting of the spell, but we'll see when we see it played :)
No duplicates. Youll always get 1 minion of each bonus effect, hence why it doesnt say "RANDOM bonus effects".
Edit: and yes the order is random.
