Second, I wanted to point out that the txt file doesn't tell you what the C/A and P/A buttons do, and your screen shots doesn't have them
TCGplayer is lower still, with unopened English listings starting at $221.99 shipped
There are endless cards in the format with massive mana values that do a splashy thing, so keeping these on the list doesnt make a ton of sense
Tell what you think though in the comments below
You must first head to the relevant Power Spot and beat it in a Max Battle
Thus a card that dominated the formats it was legal in or has regular play in Modern or Legacy like Atarka's Command, Wild Cantor, Burning-Tree Emissary, Huntmaster of the Fells, Manamorphose, or Bloodbraid Elf, would still need to prove it's chops at the kitchen table
