Like most Magic: The Gathering cards, the value of Vigor depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Fallout)
The genre shift required new mechanics and factions, but has allowed the game to bring back some old enemies too
Before you play your first game of Magic: The Gathering, it helps to know the main types of MTG card
From an investors vantage point, Leafeon ex is a deposit you wont regretits blend of nostalgia (hello, original Eeveelution fans!), solid niche play in Grass decks, and a pull rate as scarce as a rare bloom in the wild all feed the demand
BUT if the strategy/theme involves untap/tap effects like Intruder Alarm & Faces of the Past, this card makes more sense (although it still needs haste from Lightning Greaves)
All common, uncommon, and rare cards can come with a standard non-foil, regular holofoil, Poke Ball holofoil, or Master Ball holofoil finish
