It's physical move pool is by no means superior. This is saying 72 is better than it's 129 sp. atk. All Keldeo has on the Physical side is Swords Dance, Aqua Jet, Close Combat, Sacred Sword (If stat drops aren't appealing), Aqua Tail (if priority isn't appealing (lol)) and that's essentially it. This coupled with low attack clearly makes special the superior option (Unless you wana take a gamble with swords dance). It's special move pool is really lacking too though but it's enough to get the job done (Calm Mind with great sp. atk and decent enough sp. def along with STAB Hydro Pump and Secret Sword). And Ninetails is severally damaged if switched on to Keldeo's Sword or Pump and if it switches in on Calm Mind it fails to do to much in retaliation.Actually, my team in DW does not have a Keldeo check, because as long as the weather isn't rain, Keldeo loses one powerful STAB, and (Secret/Scared?) Sword only has 85 base power. Because of this, I could defeat it with my Ninetales. Also, there are a bunch of physical Keldeos in DW probably due to its superior physical movepool.
Hoping resolution form doesn't change around stats myself. I'd rather not have an attack stat boost and have to have secret sword.
Also hoping Keldeo won't be banned to Ubers. It's special Terrakion with a different benefit from weather. Terrakion get's special defense boost in sand while Keldeo get's hard hitting STAB. I mean I get the counter are kinda hard to come by but there's always wear down with hazards and out speed it I guess...
