pokémon - trading card game: mega evolution booster box TCG: Elite Trainer (Each booster pack contains 10 game cards Pokemon Mega Evolutions Booster Bundle

Zeraora has the ability to move Energy cards from your discard pile onto monsters, making it a powerful ally in the circulation of Energy for the $11.77 it tends to cost right now

The deck also has a few enchantment tutor effects to help you get the shrines into your hand

Not even the most popular cards are safe from their value declining from being worth more than a modern art piece to less than a single booster box

The largest act of defiance of this trope is Siegfried Schrder, who went so far as to hack the Kaiba Corp card database to recognize an illegal card, and reprogrammed its effect to be ridiculously overpowered (it forces the opponent to discard half their deck each turn, and that's the tip of the iceberg)
