This in-game card organizer allows you to add up to 10 cards to a Pokemon and keep them all visible. There is also a compartment for the damage indicators. Print it out 6 times (5 x bank, 1 x active position) to easily swap the Pokemon with cards and damage indicators between the bank and active position.
The card organizers are stackable for storage.

To use this organizer with sleeves you can easy increase the width in the slicer a bit.
