Monk
Base Class: Monk

The destiny is a deck of cards, and you never know what hand you will draw tomorrow. You have learned to tap into the collective subconsciousness of all living things and use this strange knowledge to inscribe Qi Cards - magical playing cards that hold the power of Cantrips

Qi Cards

At 3rd level you can spend 1 hour and 1 gp worth of materials to create a qi card using the calligraphers tools or painters kit, inscribing it with one cantrip of your choice from any class' spell list.
After finishing a short rest, you can prepare a number of Qi Cards equal to your Wisdom Modifier + one third your monk level, rounded down (minimum of one). While you hold a prepared qi card, or a deck that contains such card, you can cast the cantrip inscribed in it without any material components. Wisdom is your spellcasting ability for the cantrips inscribed within the Qi Cards. 
Casting any of the cantrips that takes an action to cast using a Qi Card counts as an attack action for the purposes of your monk class features such as Flurry of Blows.

Trap Card

When you reach the 6th level, you can use your action and expend 1 ki to place prepared Qi Card on any surface within your reach, setting up a trap card. The cantrip inscribed in this card must require a saving throw, deal damage on a failed save, and can't require concentration. Setting up a trapped card in a space that already contains one deactivates the previous card. You can also use your bonus action to deactivate one trap card that you can see.
When a creature you didn't designate while setting the trap enters the space of one of your trap cards, the card activates and its cantrip is cast, targeting the creature that entered the card's space. You are aware of any of your trap cards being activated immediately. If you can see the card, you can use your reaction and expend 1 Ki Point to impose disadvantage on the cantrip's saving throw. 

After a trap card is activated or deactivated, it is immediately teleported back into your possession. 

Focus of the Four Kings

Starting at the 11th level, your focus on the cantrips is enhanced by the clarity of your mind. If a cantrip requires your concentration, its duration becomes 24 hours. Additionally, when any of your Qi Cards that are on the same plane of existence as you deals damage to a creature, you can use your reaction to teleport the nearest unoccupied space to one of the affected creatures. 

Heart of Cards

At 17th level, you let the heart of cards guide you in the most critical moments. When you take the Attack action in which you replaced both of your attacks with Qi Card tosses, you can use your bonus action to prepare one Qi Card of your choice, replacing it with a Qi Card that was prepared up until now. 
Additionally, you can use your action and expend 2 Ki Points to select one trap card of your choice and one creature that's within the range of the card's inscribed cantrip. All of your trap cards are activated, and the creature is targeted by the selected card's cantrip. If the creature fails its saving throw, it's affected by the cantrip, but it takes an amount of damage equal to four Martial Arts die for every activated trap card that it can see instead of damage it would normally take. On a success, it takes half as much damage
