I wasn’t sold on Burgle Rogue, but there’s some life to it with these cards. I think a lot of people forget Swashburglar is in the Core Set. A 1 mana Pirate can help enable a lot of these synergies. Not to mention Wand Thief is still in Standard.
Contraband Stash feels like the weakest of these 3 cards as more of a value/greed option. That’s something typically Rogue struggles with. Wildpaw Gnoll and Double Agent could be really powerful though.
