Like most Magic: The Gathering cards, the value of Chief of the Edge 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 (Khans of Tarkir)
But even if your opponent never draws an extra card, an instant-speed two-power that can also remove a one toughness creature is fantastic on its own
One thing that really helped me when I was a new player was to stop thinking of removal as only boardwipes and creature removal such as Infernal Grasp
That said, Rainbow Rare cards are typically among the most uncommon in any given Pokmon TCG collection
So why oh why must they be dressed so stupidly
