Voidlord is a solid enough card, at 1 mana.
Darkbomb was a 2 mana deal 3, and was quite good in its time.
This card takes essentially 4 mana in solid cards, compresses them into a single card, and doesn't change the price, meaning instead of needing 3 cards, you just need one, and the 'other two cards' you've drawn instead can be something else instead.
I remember a time where this would have been meta dominating, but as it is, I'm out of touch with regards to power creep. At worst, I'd call it a very reasonable card.
