yugioh eternal duelist soul dragon deck The From Legendary Dragon Decks set Initial Deck (EDS) - Yugipedia

Powerful but not able to grab financial traction

If we are talking about all formats combined then I am very much the one who underrates Jace and Goyf

An ungraded, holographic First Edition Charizard card from the base set (the very rare card I sold on eBay when I was a kid) is worth a few thousand dollars

Mindless Null While this card isn't a Vampire, it is a "Vampire matters" card and it has a good story, so I'm going to tell it

It is proactive, utility, and value and so ticks a lot of cube boxes

For only the cost of one, you can play this character that can then be exerted in order to spend less cost on the next character you play that turn
