So basically a mini-kingsbane? You don't have to re-draw it like kingsbane, but to keep it infinite you have to keep playing non-rogue cards, so much much worse than kingsbane against another rogue or against any weapon removal.
This actually looks really good when your playing a burgle oriented deck, especially in wild. Is able to be buffed with Deadly Poison, and (in wild) Tinker's Sharpsword Oil. looks like a fun and strong card for rogue.
