The thing is, its hard to compare to Charizard really
Its a good rat and a good rogue, especially if you care about dealing combat damage or about the saboteur triggers
1, 69, 420, and 500, for instance, will likely all be sold for over the average market value
Dark Illusion, Fiendish Chain, Skill Prisoner good negate cards, Dark Illusion works for Spells/Traps and monster effects, and fiendish chain also stops the monster from attacking which makes it easy to destroy it later with the monster effects of the barrel dragons that you might get anyway, Skill Prisoner is great to protect the effect monsters or the field spell and it works twice
The only real issue I see with these cards is that when you remove them from the pack, there may be a factory nick on one of the corners
