Good card. Interesting that it has this new "steal" synergy as well as the Pirate-tribe. The most intriguing thing is that it could work in a deck without either of those, it's a value card. Surely won't find a place in Miracle but I'd play it in a Reno deck, maybe even a control one.
I don't like that this is reallly, really similar to Undercity Huckerster, But I do like everything else about it... I honestly think Burgle Rogue will become a thing, it has just enough to take off. This card is exactly what Rogues want to be doing on turn 1, I've always thought a card like Webspinner would fit their playstyle really well. Rogues run out of steam really fast so a turn one play that nets you another card is really ideal. The same way that Undercity Huckster is strong.
