Here are some words that might fit the bill (not sure if any of them would be a good fit though)
talent, ability, virtue, capability, capacity, endowment, potentiality, force
It's tough really... ideally we'd want a word that incorporated the meaning of a possession (like an item, weapon or armor), the concept of an ability (like a power), the idea of having knowledge (spells), the idea of help from friends (allies) or from the gods (blessings).
There may not even be a word like this in the English language. Maybe "powers" should have been called "talents", then the word "power" could have been used for this.

Is there any collective word that covers both cards and powers? Having to write "cards/powers" everywhere is a minor annoyanace!
E.g. ...If you have a XXX that lets you evade the card you're encountering...
You can usually just say "Power", since most of the things you care about are in "Powers" blocks on cards.
