Are the legendaries Prince Malchezaar adds to my deck all different?

Are the 5 legendary minions which Prince Malchezaar adds to my deck all different or can two or even more be the same minion? Can I e.g. rely on Reno to heal me up?

Prince Malchezaar follows the Deckbuildung rules, which means that

• no legendary that is already in your deck is added
• five differerent legendaries are added
• no legendaries of other classes are added

As @CobaltZorch mentioned in the comments, Prince Malchezaar adds the cards after the mulligan. This makes it possible that a legendary that you already have in your hand is added to the deck. The legendaries in your deck will stil be unique though, so Reno etc. will still work without surprises.

Prince Malchezaar will not add duplicate legendaries to your deck, so it is safe to play Reno in your deck. It will also only add neutral and the same class legendaries to you deck.
