This Base-Neo deck centers around the incredible value of Base Set Ninetales:
Dealing 80 damage (which one-shots most of the Pokemon in this meta) at the cost of just 1 Fire Energy, on a Stage 1 with 80hp with a "Gust of Wind attack" as well with Lure, and only 1 Retreat Cost, is very powerful in this set.
Light Flareon's Warm Up and Exp. All Trainers help boost the Ninetales to get energies stacked as quickly as possible to start Fire Blasting as early as possible, and the Magmars are low-energy cost, high-value basics for the early and mid game.
Healing Field helps Ninetales shed some chip damage while it's in the active position, and you're not too worried about your opponent getting much value out of it since they'll most likely either have no damage, or be KOed by a Fire Blast.
