Any time an Actor learns a Skill, they gain that skill’s card. Likewise, whenever they forget a skill, they lose that skill’s card.

An Actor can learn the same skill multiple times to get multiple copies of the same card.

Any skill learned mid-battle will automatically be forgotten at the end of the battle, meaning cards can be temporarily added to the deck mid-battle.

Make sure to give them enough skills before the first battle that they can run a deck.
