This is something we're continuing to experiment with, so you may see some future cards that share a set code but don't have an expansion symbol on the card
rather, its the fact that it gives you direct insight into exactly what cards your opponent has, allowing you to strategise around what they have available
Your thumbs help press the top arch of the "bridge," preventing the cards from flying upwards
That is why it is important not to judge solely by cheap prices or general vibes, but to comprehensively look at the printing, paper quality, holo processing, photos, descriptions, and seller information
The process requires time, so it may take 15 to 90 business days for your Pokmon cards to receive a grade and be returned to you, depending on the submission tier
