one piece eb03 booster box Card Game EB-03 Extra : Toys & Games 03 Heroines Edition One Piece Trading Card Game

This isnt an unusual structure for Magic: The Gathering product

Echoes of Eternity can copy your mana rocks and nonlegendary creature spells, plus you turn removal spells like Null Elemental Blast into 2-for-1 bargains

If your card grades PSA 10, you'll nearly triple your money even after grading costs

I've always been convinced since the day it came out that Hearthstone's Iron Juggernaut (the first card in the game to shuffle a card into your opponent's deck) was inspired by this card, but while this type of effect works in digital card games with no issues, there are a lot of reasons this design doesn't work too great for a physical card game
