What a blast from the past. This card wont see much use unless you have some sneaky means of gaining advantage. From what I've seen over the past few months this card is best used in some kind of Chaos build or in some kind of Pot Of Avarice build. If you aren't using it in either than there is no point.
If you are using it in the chaos build it's simple. Discard one and you'll get 2 to your hand. This provides a light in the graveyard for the sorcerer. It will also thin out the deck, as well as provide a lv5 if needed for meta.
In the Pot Of Avarice build it gets even more simple. All you need to do is discard one to get the others. Once you do that just discard them into the grave by any means to fill in the 5 monsters needed.
All in all give it a spin if you are running either of these decks.
Chaos build: 2.5/5
Pot Of Avarice build: 2.5/5
