You get a card when it dies. Doesn't matter what the other class is, any card is better than nothing.
I like the card, but that moment you get sense demons it's going to make you have to laugh
It won't work in any deck because it's a 2/2 with random outcomes giving you cards that have possibly no synergy whatsoever with what you're trying to do. How much burgle saw play? This is even worse actually. Yeah, that one trolden video with burgle etc etc, it's a joke RNG card.
This is not Dark Peddler for rogue, Dark Peddler gives you specific cards, 1 mana cost cards are generally strong for their cost and you have the increased chance of getting cards from YOUR class.
If this card gave you cards from your own class too then it would be interesting. I don't see why you wouldn't play loot hoarder instead. Cards from your own deck will generally be better for you than say getting a paladin secret or something unplayable by playing a 2/2.
Oh man I would be so down with it giving you a random rogue class card over a mini burgle.
