On a Dragon Dance set, running 0 speed seems like a horrible idea. Without speed, +1 Scrafty with 0 speed reaches 228, one point below Adamant Emboar. Without attack, Scrafty is weak af. See:
+1 252 Atk Scrafty High Jump Kick vs. 0 HP / 0 Def Clawitzer: 276-325 (97.5 - 114.8%) -- 81.3% chance to OHKO
+1 0 Atk Scrafty High Jump Kick vs. 0 HP / 0 Def Clawitzer: 213-252 (75.2 - 89%) -- guaranteed 2HKO
That's not even counting for the fact that it seems you would be running Drain Punch over High Jump Kick. You definitely want max speed and attack on DD Scrafty as without it becomes way less of a sweeper and easier to revenge be kill.
