Cards signify which Art (effect) and Realm (what or whom the effect works on) the character uses. The Player plays these cards. Multiple Realms can be combined, though they cost extra Glamour.
The Player has one Art card "for each dot in Arts" that she or he has. The same goes for Realm dots. The Player also has Bunk cards, in a separate deck, (see below) equal to the total dots in her/his Arts.
The Player also draws a Bunk card (what is required for the Cantrip to work) from a deck of Bunk cards. If the Player cannot or will not fulfill the Bunk, the Cantrip fails. By spending Glamour, the Player can draw two Bunk cards. Both must be fulfilled, but the Player can get more successes.
The Player then describes the effect they wish to achieve. Get creative, judgement is up to the Storyteller.
Depending on the effect, the Player may have to overcome Banality. The Player rolls dice specified by the cards. Art tells the Attribute, Realm the Ability. Target(s) may resist using their own Banality.
Discard, refresh (the latter only after a thorough rest, till then, you always place all the cards except for one you choose into your hand, thus slowly depleting your deck.) The number of cards available are limited by dots etc.
There are "Advanced" complications, such as suits matching resulting in extra successes etc.
Bunks included stuff like tearing a four leaf clover into four separate pieces etc.
