Your patron is Chaos, a primordial force that is believed existed even before the first Gods were born. Some think they might have been also originated from it and later used it as a tool to create the world as everyone knows it today. Chaos is ever-changing and always in motion, impossible to read and comprehend for anyone.

When you bind yourself to this entity, you may start to feel the need to do things out of the ordinary, things you would never have done otherwise, try new experiences, but without exceeding or crossing lines, keeping everything in balance.

Chaotic Spells

1st-level Agent of Chaos feature

You learn additional spells when you reach certain levels in this class, as shown on the Chaotic Spells table. Each of these spells counts as a warlock spell for you, but it doesn't count against the number of warlock spells you know. Additionally, whenever you gain a warlock level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be a spell that deals only acid, cold, fire, force, lightning, poison or thunder damage.

Chaos Dealer

1st-level Agent of Chaos feature

Your patron bestows upon you a token of its unfathomableness, the Deck of Chaos. This deck contains 20 blank cards, each with overwhelming wild magic. Starting at 1st level, you may roll on the Chaos' Manifestation table 5 times. For each roll you make, one of the cards in the deck gets inscribed with the resulting effect.
On each subsequent level in this subclass, your affinity for Chaos increases considerably, allowing you to inscribe 5 additional cards with different effects from an enhanced Chaos' Manifestation table. Additionally, whenever you roll on a new Chaos' Manifestation table, you may forgo one of your rolls and choose one effect from the previous table and inscribe one of the cards with it instead.

As a free Interaction with an Object, you can summon the Deck of Chaos, which starts fluctuating around you. Immediately after you summon it, and as a free Action on each of your turns, you can roll a d20 and command the deck to deal you the resulting card. If you would roll a card that is still part of your hand, you may roll another d20 and be dealt a different card. Any card you are dealt hovers over your head waiting to be used. Causing an inscribed card to manifest its effects requires a specific action, depending on the power dwelling in it, as specified in the Chaos' Manifestation table, after which the card turns blank and gets back in the deck. You may also expend one of your spell slots to mirror the card's effect without consuming its power. 

Whether the card you roll is a blank one or an inscribed one, you can use your Action to grab the card and make a ranged weapon attack with it. For this purpose, the Deck of Chaos counts as a simple weapon with the range (40/80) property. On a hit, each card deals 1d6 piercing damage. If you have any feature that allows you to make any amount of extra attacks whenever you take the Attack action on your turn, you may use the same card for any additional attack; after that, the card gets shuffled back in the deck.
You may fold your hand as a Bonus Action or carry it over onto your next turn requiring no action. However, your hand can't exceed a number of cards equal to your proficiency bonus.
The cards' damage increases by 1d6 when you reach 6th level (2d6), 10th level (3d6), and 14th level (4d6).

You may use a number of inscribed cards equal to your proficiency bonus and regain all expended cards after finishing a long rest.
