After the nerf, Pen Flinger has been showing up in far fewer decks. Thank heavens... But, he still does make the cut in this deck which helped us complete both the Everyone's In Here! achievement to fill our entire board with Gruntled Patrons, and the Magnets, How Do They Work? achievement to play 12 cards in a single turn as Rogue.

With help from Silverleaf Poison on the Swinetusk Shank and a ton of cheap combo/battlecry cards to pair with Field Contact, it's possible to cycle through the deck like mad. Efficient Octo-bots triggered by Pen Flingers help ensure our Gruntled Patrons and/or spells to bounce Pen Flinger are cheap enough to keep bouncing him so that we can trigger enough Gruntled Patrons to fill the board. Scabbs Cutterbutter is in the deck to help get Field Contact and/or Swinetusk Shank out a little faster, or to help draw through the deck even more after Field Contact.

On the combo turn, you drop the Gruntled Patrons onto your board, trigger their Frenzy with Pen Flinger, and bounce them back with a spell. Repeat till there is only the final Patron needed, and use Backstab to trigger the final Patron Frenzy needed to fill the board. End your turn with a full board of patrons, and you'll have the achievement!

If you'd like to see the deck in action as we completed the Everyone's In Here! achievement on stream (the gameplay of completing Magnets, How Do They Work? is in the background during the intro as well!), check out the highlight at https://youtu.be/2Bc-f7fyuBQ or below. Best of luck, and have fun experimenting!
