The problem is, most of those really fun cards cant be put in a deck in traditional formats because they arent competitive enough for the metagame
The centre piece of this model requires supports
Yuffie, Materia Hunter steals an artifact while equipping herself, and is an aggressive body with an aggressive Ninjutsu ability, and Barret Wallace rewards you for having a ton of equipped creatures out by dealing massive damage
Like most Pokmon cards, the value of Paras depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Supreme Victors)
The only other difference is you're stealing from the grave, not their top deck, so you have to make sure you do plenty of milling
