The Fey Trickster

A mischievous archfey, the soul of a master-thief or a god of trickery. The patron for this warlock pact can take many forms.
The patron embodied the spirit of change, being completely unreliable and able to change on a whim.

Each time the warlock completes a long rest, he must roll a d4 to determine his class powers for the day ahead. Only one type of ability-set is available at any time. 
The warlock is unable to have abilities from different ability-sets at any time (ie. if Trickery is rolled on the die, all class level abilities will be Trickery till next reset).

These powers are school into four different groups:
Trickery - Harnessing the more playful nature of being carefree, cheating for fun and misdirection. This set consists of Manifest Trickster, Emerald Step, Beguiling Strikes and Changes Fates.
Fey - The powers of the Fey Wilds in all their unstable and ever-changing ways. This set consists of Charming Presence, Fey Instincts, Slippery Mind and Unassailable Majesty. 
Illusion - Focusing on changing the way things are perceived in the world around you and everyone else. This set consists of Stage Magic, Warding Illusion, Illusion Master and Dark Dismay. 
Subterfuge - The darker shadowy side of tricking and stealing. This set consists of Thief's Instinct, Thief's Talent, Armor of Shades and Shadowmaster.

1st Level Features

At 1st level, the following ability become available for the warlock. 

1 - Trickery: Manifest Trickster - As an action, you create a perfect illusion of yourself that lasts for 1 minute, or until you lose your concentration (as if you were concentrating on a spell). The illusion appears in an unoccupied space that you can see within 30 feet of you. As a bonus action on your turn, you can move the illusion up to 30 feet to a space you can see, but it must remain within 120 feet of you.

For the duration, you can cast spells as though you were in the illusion’s space, but you must use your own senses. Additionally, when both you and your illusion are within 5 feet of a creature that can see the illusion, you have advantage on attack rolls against that creature, given how distracting the illusion is to the target.

This ability is usable once per short rest.

2 - Fey: Charming Presence - Your patron bestows upon you the ability to project the beguiling presence of the fey. As an action, you can cause each creature in a 20-foot cone originating from you to make a Wisdom saving throw against your warlock spell save DC. The creatures that fail their saving throws are all charmed by you until the end of your next turn.
Creatures charmed by you are unable to take any other actions, than spending their turn moving as close as possible towards you.

This ability can be used a number of times equal to your Proficiency modifier per long rest.

3 - Illusion: Stage Magic - Your patron grants you the Prestidigitation cantrip. The cantrip doesn’t count against your number of cantrips known.
Additionally when you cast the spell, you are able to choose this additional option, and you can cast the spell without the need for verbal or somatic components.:

• You change the appearance of an object you touch to that of another object you have seen before. Both objects must fit into your hand.
  Any creature who examines the object can make an Investigation check against your spell save DC. On a success, they see through the illusion.
  The effect wears off after 1 minute

In addition, the warlock is able to cast Mirror Image once at its lowest level, and you must finish a long rest before you can cast it in this way again.

4 - Subterfuge: Thief's Intuition - Your patron imparts some of their grace, choose either Sleight of Hand or Stealth to gain proficiency in. 
Additionally, prior to making a skill check or saving throw that you don't have proficiency in, you may use your reaction to add your proficiency bonus to the roll.
This feature can be used a number of times equal to your Charisma modifier, and all expended uses are restored when you finish a short or long rest.
