First, they are separated by Type.
Old (Base set to E-readers) Pokemon cards are placed, separately, before any of new cards.
Since November, all of my cards have been put into their own binders by type...
Rares, Lv X, Commons & Uncommons are mixed together, organized by evolution...
1)Old Grass
2)New Grass (Too many, I had to separate them into 2 binders)
3)Psychic
4)Colorless and Eevee-volutions
5)Fire
6)Fighting
7)Water
8)Electric and Metal
9)Old Trainers
10)New Trainers
11)Dark, Galactic, Arceus, and Rumble
12)Yugioh cards and what not
Most of the binders are different colors, and have Booster pack foil art in the front to show what could be inside.
E.g. The Blue water binder has a Gyarados (eX HOolon Phantoms) ,eX Power Keepers Walrein, and Secret Wonders Weavile: packs in the front.
At a City Championship, I won the raffle for the Giratina binder.
I haven't decided what to put in there just yet. Any suggestions?
