I've seen this set and spread
here so for further explanation read this post; basically this set capitalizes on pult's great attack stat and stab dragon darts - combined with dragon fang - to soundly 2hko av tornadus. this set can either hit torn-t with dracometeor into dragon fang, which deals around 90% min from full, or, if tornt is statused, pressure it with hex until its in darts range.
draco meteor + dragon darts is the preferred combination for the particular task of luring av torn-t because no-one expects pult to run both at the same time. hex+twave can ruin torn-t as well, but doesn't have the same KO potential
116 Atk Dragon Fang Dragapult Dragon Darts (2 hits) vs. 248 HP / 4 Def Tornadus-Therian: 204-240 (56.5 - 66.4%) -- approx. 2HKO
140 SpA Dragon Fang Dragapult Draco Meteor vs. 248 HP / 92 SpD Assault Vest Tornadus-Therian: 127-151 (35.1 - 41.8%) -- guaranteed 3HKO
alternatively,
140 SpA Dragapult Hex (130 BP) vs. 248 HP / 92 SpD Assault Vest Tornadus-Therian: 106-126 (29.3 - 34.9%) -- 10.1% chance to 3HKO
for more damage with ghost stab or draco meteor, a spread on 116 atk / 232 spatk / 160 spe can be run: it still outspeeds koko but maximizes power.
of course, if the team already does a good job spreading status, hex can be run without twave, but for the sake of luring tornt, either
twave+hex pressure into dragon darts, or even better,
draco meteor into dragon darts (91.7 - 108.2%)
