By paying 2 EXP, a player gains their Gadget Card, by turning it over to the colorful side.
Gadget Cards can only be gained once.
Place the Gadget Card on your Sidekick Card, to the top-right corner, for the Sidekick to use its abilities.
All Sidekicks can only Equip a single Gadget Card.
The only Sidekick that can't use a Gadget Card is Hi-Q.
