The Alchemist Class Deck Damiel has an ability that reads:
When you would banish a card that has the Alchemical trait or a spell for its power, you
may recharge it instead.
How should this be read? Is is When you would banish a card that has the Alchemical trait for its power, or anytime you would banish a card that has the Alchemical trait?
If it is anytime you would banish a card that has the Alchemical trait then Damiel as a MindChemist can become extremely powerful as he can recharge a card with the Alchemical trait to DEX to any "Mental" skill or INT to any "Physical" skill.
On the other hand if it is When you would banish a card that has the Alchemical trait for its power, then the Staff Sling like weapons become pretty much pointless as they make you banish your cards with the Alchemical trait.
It's "When you would banish a card that has the alchemical trait for its power." So if you banish it for something else, like a character power or another card, you don't get to recharge it.
Playing CardsAnyone can play a card whenever the card allows it. Playing a card means using a power on that card by revealing, displaying, discarding, recharging, burying, or banishing that card or by performing another action specified by that card. Activating a power on a displayed card also counts as playing it. If a power says using it counts as playing a boon, it counts as playing a card. Doing something with a card that does not use a power on that card does not count as playing that card. For example, when Seelah discards a spell to use a power on her character card, the discarded card does not count as being played (meaning she also can’t recharge it).
That's where the reference is about playing cards and using the powers on cards vs using a character's power with cards having specific traits or specific types. (Like that example of Seelah using her power.)
