Like most Pokmon cards, the value of Golbat 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 (Delta Species)
Each capsule slot has a corresponding icon to quickly add or remove your chaos tokens from your chaos bag
If you steal the Rose token with Galaxy-Eyes Cipher Dragon, it will automatically become his ATK 3000, and you can use his ATK 3000 instead of the halved main body, and you can also revive monsters with ATK 3000
The relationship between total population, gem rate, and market value is nuanced and specific to each card, and the collectors who take the time to understand those relationships are the ones who make the best decisions about what to buy, what to submit, and what to hold
