Oooh, shiny...
Anyways, shiny Vulpix is definitely an interesting card to use. Stat-wise, 60 HP is common for a Basic, +10 Weakness to :water: hurts, but is a small Weakness and not x2 like SP, no Resistance (common), and costing :colorless to Retreat. Shiny Vulpix comes with 3 fun attacks to use. Find Wildfire lets you get 2 :fire: Energy out of your deck for free, which lets you easily ensure you have Energy the next turn. Brushfire deals a simple 10 for :fire:, and lets you do 10 damage to each of your opponent's Benched :grass: Pokemon, which is nice given that Torterra and Scizor are still relatively popular. Inflame is a bit underpowered at :fire::colorless for 30, especially since you have to discard an Energy from your hand to use it.
Modified - 7/10 (I'd use this Vulpix over any others, but its evolution, Ninetales, isn't played much, if at all)
Limited - 9/10 (Great 3 attacks to choose from, fits nicely in a :fire:-oriented deck)
Unlimited - 1/10 (Lol, no Vulpix or Ninetales to use here. But, if you feel the urge to use Ninetales for whatever reason, this Vulpix is great to use with it)
