Curious as to the rise oftbh. For the longest time it was outclassed by Hecidueye and Fire Tauros as Scarf Fighters but I wonder what changed to see it higher up in viability.
well, the biggest answer to this is just that pokemon like hecid, redbull, and pawmot don't run scarf often anymore, hecid has been favoring SD sets for a while now, pawmot often doesn't want to be locked into doubleshock and can honestly provide better speed control with LO iron fist mach punch, and scarf redbull has always been kinda fraudulent. passimian is good though! one big thing that helps it is having access to knock off and u-turn while having a better speed tier than hecid, and access to defiant is very nice to keep intimidate, webs, and parting shot from totally ruining your day
