Superficially Ivor fits with most forth ring decks. High value, abomination keyword, and strong huckster skill are all nice. However, beyond that he's really not that impressive compared to other options. Even with a hex, he's only 2 stud, 4 influence, and huckster 3. That's enough influence to make him a target but not enough bullets to fend for himself. Plus, at 9 cost and 2 upkeep he's outrageously expensive for what you're getting. Most other dudes with that price tag will have a strong ability to make it more worth while, while Ivor gets a buff that is effectively useless. 2 stud isn't particularly scary, and the Huckster 3 buff is nearly worthless considering no halfway decent huckster deck would run hexes/values that a Huckster 2 couldn't reliably cast.
Bottom line: Unimpressive and not worth the cost.
