The Daemon who Dares
Damage that doesn't go to face doesn't trigger spectacle, which is kind of a big deal against standard RDW, which is pretty reliant on spectacle. On top of which, Risk Factor still sees a lot of in standard RDW. Risk Factor is a dead card with the Wanderer in play.Oh, I didn't realize we were talking standard. I honestly wonder if standard doesn't have too many creatures for the wanderer to be good? It either gets killed, or ignored, depending on the situation. Best case scenario it's basically a 4-mana gain-six (or maybe a 4-mana gain 3, kill a steam-kin), and I'm not sure that's good enough?
There's also Rakdos Burn which runs sovereign's bite and is just as reliant on spectacle. Izzet counterburn doesn't see as much play but has a higher tendency to rely on Electrostatic Field which she also shuts down
Probably sideboard card as best, but if burn decks remain popular I could see her being decent sideboard tech.
