There is none. Blizzard stated it's a bug and should be ignored. Several people on r/Hearthstone have confirmed this, so no need to worry about a missing reward.
Personally, I love meme cards if they are tasteful. This is the perfect example of a tasteful meme card. The card name is tongue-in-cheek, but the card effect actually does something and it has something to do with the card's name. Art is excellent too, which just proved my point a funny card can still be as polished as a normal card. Well done! I think it is a little on the weak side. I'd bump it down to 3 mana.

Genuinely one of the major reasons why I didn't participate. It's that well-designed of a card.

At 3 mana it's strictly better than Arcane Intellect, but maybe that's okay? Rogues are known for having some of the best card-draw engines.

Dunno if meme names are allowed. Might also be underwhelming in originality despite the name.
