Volcanion needs 10 damage counters to do 250 damage. How do we do that? With Welder and Old Cemetery to pile on the damage as well as Jynx and Spiritomb to move the extra 2 damage counters. Cape and Abomasnow might help you not get immediately knocked out. Dowsing Machine could also be substituted for a Scramble Switch with Blend Energy turning Spiritomb into a backup attacker. Please let me know if there is a better way to build this deck.
