Say how many cards you've collected. Even if they're some that are the same, or you could say how many pokemon you have. Not counting more of the same kind of pokemon.
My collection is so daunting and ever growing that I do not dare count how many cards I have. This upcoming Saturday (Feb. 4) will see 162+ cards being added to my collection.
Huh let's see here... I have all of 9 cards. I used to have enough to make 2 decks, but that was way back. Now I only have the cards I got in a booster pack.
