Like most Pokmon cards, the value of Braviary 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 (Surging Sparks)
Its very rare that codes actually go live and offer free stuff to the entire community
Why Its Important: Avoid Impulse Purchases: Rare Pokmon cards, especially those youve been eyeing for a while, can be tempting
Some cards, like Archfiend of the Dross, use oil counters as a doom clock (when its over, you lose) by losing a counter each turn
If a card is later mentioned that you dont have, you can always craft the card in the Pokmon TCG Pocket for yourself
So no Magic card here is so bad that you cant play it
