I'm aware of this, I even mentioned bulbapedia in my question. I'm reseting my 3ds/2ds for a totally new friend safari every time. This will (potentially) give my a different type/pokemon for slot 1. What seems odd is that every time I get another dark safari, Mightyena is slot 1. The other 10% of the time I've had nuzleaf. Bulbapedia has been wrong before and these numbers may just be an assumption
