Where it does shine is in decks that use the graveyard, especially Reanimator builds
Rigo, Streetwise Mentor itself gives you a card, and its flexible enough that you can either focus on the attack triggers and saboteur effects (Delney, Streetwise Lookout and Enduring Curiosity, for example), or you can try to overwhelm your opponents with sheer numbers in a token build
The biggest drawback to running these is how quickly they make you into a target, which only proves their power
