Jackpot

There's a certain slyness that comes with working at a Casino. That wicked edge that allows a dealer to dissect someone playing poker at their table and separate truths from bluffs. These rogues live on the art of the game and the philosophy "The House always Wins".

Cheater's Tool

Starting at 3rd level, you've developed a plethora of tricks and tools to allow you to guarantee your victory in any game. These "guarantees" take the form of Trick Dice, which are each a d6. You have a number of these Dice equal to twice your proficiency bonus. 

Some of your tools expend the Trick die they use, as specified in a Tool's description, and you can't use a tool if it requires you to use a die when your dice are all expended. You regain all your expended Trick dice when you finish a long rest.

When you reach certain levels in this class, the size of your Trick Dice increases: at 5th level (d8), 11th level (d10), and 17th level (d12).

Razor Cards. After making an attack you can use your bonus action to expend Trick Die up to your proficiency to make an attack using a Razor Card. The Razor card does damage equal to the amount of Trick Die you expended plus your Dexterity Modifier. When an opponent is hit by this you gain advantage on your next attack against them. 

Dealer's Sight. You gain proficiency in Perception and Insight. Whenever you make a Perception or Insight check you can spend a Trick Die and add it to the roll.

Poker Face. You gain proficiency in Deception. Whenever you make a Deception you can spend a Trick Die and add it to the roll.

The House Always Wins

At 9th level you've truly come to appreciate the art of chance granting you new abilities with your Trick die.

Double or Nothing. Risk becomes your safest place. When rolling with disadvantage you gain a +5 to hit, you can still gain sneak attack, and if you hit you double the damage dealt from your Sneak Attack.

Cut Shuffle. When an opponent you've hit with you Razor Cards makes a melee attack against you can use your reaction to disengage and move 30 ft.

Croupier

At 13th level Your presence's so appealing that the first time you meet anyone you get advantage on Persuasion and Deception rolls.

Royal Flush

At 17th level when you roll a Natural Twenty on anything you can store some of that luck to use later in combat.
