1st edition pokemon booster box sealed Back in 1999 you could buy an entire Base Set for $500, $550 for a box, a Charizard for $100, etc. Crazy how far we've come! : r/PokemonTCG 320: 1999 Pokémon Base Set

The Magic card with the longest rules text used to be Bureaucracy (769 characters)

Whenever Blightwing Whelp deals combat damage to a player, seek a card with mana value equal to the number of poison counters that player has

Theres another ban here, and its explosive, but in a different way

While most Power Nine cards are banned in every format except Vintage, Timetwister remains the only one legal in Legacy and Commander, making it an essential piece for competitive blue players

While a lot of this cards price is predicated on scarcity and it sees less play than Aura Shards, I think this has cross-format applicability with casual and more of a future

There are several more of these from back then, and many in future releases as well, so expect another one when I get fed up with seeing dumb things on that TCG bottom line again.
