Prior the errata, Som'er and crew were the best card drawing mechanism in the game. In fact, it was actually possible to draw your entire deck into your hand and then drop only the 13's and Red Joker back into your deck, ensuring that anything you did not only went off, but decimated your opponent.
This of course resulted in the dramatic changes that have occurred. Unfortunately, with the debuffs already built into Som'er and crew, this severely weakened Gremlins in general. I fully expect that the Gremlins will see significant improvement in the next book, or they might actually see some additional errata (though I think this is less likely). However, that being said, the Voodoo Doll received a very nice piece of errata, namely giving Poison 2 to the conduited model every turn, which was a significant improvement for Zoraida and crew, so maybe additional errata is not completely out the window.
