What you do need is a clean, non-reflective surface and even lighting, because holo and reverse-holo cards throw glare that hides the exact scratches a buyer will notice the second the card arrives
This can often generate a higher value than selling the collection as a whole, as it broadens the target audience and allows more collectors to find the cards they are looking for
The clash keyword for instance can be a consistent way to do this, and its on a bunch of goblin cards youll already want to play like Adder-Staff Boggart
Professors Research in Sword & Shield has the exact same effect, but like Hop is a Supporter card, limiting its use to one turn
Pokmon TCG Phantasmal Flames will be based on the Japanese set, Inferno X
Some immediate creatures you could bring back include Kroxa, Titan of Death's Hunger, and Blood Artists for maximum value
