Gambler

Stacked Deck
Beginning at 8th level, you gain a proficiency with the Trickster's Deck, and can scrounge up such a deck whenever you take a long rest. On its surface, a trickster's deck is a martial ranged weapon dealing 1d4 slashing damage and possessing the Ammunition (60/180) and Two-Handed properties. In the hands of a Gambler, however, the deck's true power is revealed - as a bonus action, a Gambler may draw cards from the deck until they have a hand of four cards. They may throw these cards in place of mundane ones when making normal attacks, but no more than one may be thrown per round. For each card drawn, roll a 1d8 to determine what the deck yields. You can have more than one of the same card. All save DCs from the effects of a trickster's deck are determined by [8 + Intelligence Mod + Proficiency].

Winning Hand
Beginning at 13th level, you can call upon the blessings of fate and fortune, and gain potent advantages when your hand holds specific combinations of cards. The following blessings are available.
 * Two Of A Kind: When your hand contains two matching cards and you attack with one of them, you can choose to have that card ricochet to a second target within 60' of the first if it hits the original target, making a second attack with identical effects. You can still only apply your sneak attack damage to one target.
 * Three Of A Kind: When your hand contains three matching cards and you attack with one of them, you can choose to have that card ricochet to a second target within 60' of the first if it hits the original target, making a second attack with identical effects. If the second attack hits, you may ricochet one additional time You can still only apply your sneak attack damage to one target.
 * Four Of A Kind: When your hand contains four matching cards, you can expend them all as an action to make a special attack targeting every enemy within your short range with an attack. You can still only apply your sneak attack damage to one target.
 * Two Pair: When your hand contains two sets of two matching cards, you can expend one card of each pair to make a special attack in which you attack with both expended cards simultaneously. The two cards are targeted independently, and can aim for the same or different targets.
 * Royal/Rabble Flush: When your hand consists exactly of either QUEEN/DUKE/PRINCE/MAID, or THIEF/SAGE/WITCH/KNAVE, you can expend your entire hand as an action to make a special attack against a creature within range one of your cards. This attack automatically hits, and the target automatically fails its save against the attendant effect.

Always Lucky
Beginning at 18th level, once per short rest, you can choose exactly which cards you draw when you use a bonus action to draw from your trickster's deck, rather than rolling for each card.
