The Gambler

Wizards in this specialty develop their magic often on accident, and have found it inexplicably tied to gambling. These wizards use their magic seemingly at random, with the will of the cards controlling their powers. Little is known of the cause of this phenomenon, save that these wizards need only their trusty deck when casting, not some prissy wand or foolish book of spells.

Shuffled Spellbook

Your knack for gambling has allowed you to pick up some handy magical tricks. What do these tricks do? Why, that's for fate to know and us to find out! Of course, that isn't to say that you can't pick what spell you cast at a given time. Just that you don't know what spells you might know at a given time. On a long rest, learn and prepare a list of random spells equivalent to your wizard level+proficiency+spell slot total. Spells are divided proportionally to each spell level. This gives you a bit of flexibility in your methods, but I suppose the deck will decide whether or not you are of use.

Take a chance

• Starting when you choose this school at second level, you can cast spells through a deck of cards. These card must be on your person in order to cast.
• This deck of cards must be shuffled at the beginning of every long rest, and  any cards drawn must be returned into the deck.

When you cast a spell, you must draw a card from the top of your deck. This card will determine either a positive or a negative effect that is added to the spell. Check the Draw table to determine what effect the card you drew has.

Play it safe

• At sixth level, when casting a spell, you can expend an additional spell slot of equal or greater level to not have to draw from the deck.
• Additionally, when an enemy is casting a spell (The spell can force an attack roll or a saving throw), or making a weapon attack, you can use your reaction to draw a card and impose an effect on that person’s attack. Draw, and check the counter table to determine the effect.

  Counter Table	Diamonds	Clubs	Spades	Hearts
  Ace	C	C	CF	CF
  King	C	C	CF	CF
  Queen	C	C	P	P
  Jack	A	A	P	CS
  10	A	A	CS	CS

  Red Joker	The enemy instantly gains another action, and can cast another spell regardless of its level.
  Black Joker	The enemy instantly makes the person being attacked paralyzed until the end of their next turn.

   

  C - The attack instantly hits, and is a critical hit against the creature it is hitting. If the hit is a spell that requires a save, it acts as though the creature making the save rolled a natural one.

  A - The attack instantly hits.

  CF - The attack roll counts as a natural one, allowing for an opportunity attack.

  CS - You cast “CounterSpell,” at third level, if this doesn’t end the spell, you must roll. If this is drawn while trying to counter a weapon attack, nothing happens.

  P - The enemy is briefly paralyzed, forcing them to give up the attack, but they can immediately continue their turn after. If this happens when countering a spell, the spell is not cast, and they do not lose a spell slot.

Experienced Cheater

Who doesn't love a cheater? At this point, you have expanded your gambling knowledge so much that cheating comes as second nature.

• When you draw a card, you may use your bonus action immediately to draw another card once per day. Both cards get discarded, however.
• When an enemy within 20 feet uses a legendary resistance against a magical saving throw, you may draw a card as a reaction.
  • If the card is spades or hearts, the legendary resistance doesn’t take hold.
  • If you draw a diamonds or clubs, the legendary resistance takes hold.
  • if you draw a Joker of any kind, the creature is allowed to use it’s legendary resistance, and gains another use of it to replace the one it just used.

Ace up the Sleeve

• The jokers in your deck now have a 75/25 chance to become an ace. When a joker is drawn, roll a d20. If the roll is higher than 5, it turns into an ace, However, if the roll is 5 or lower, it stays a joker. A red Joker becomes an Ace of Hearts, while a black Joker becomes an ace of Spades.
• If you draw an Ace of Diamonds or Clubs, you may use your reaction to take 25 Psychic damage and turn that into an Ace of Hearts or Spades, you may choose which it turns into, but what it turns into must be currently in your deck, and removed from your deck after you use it through this ability.

Jokers Wild

Your slight of hand skills have ascended to the level that you may secretly swap your jokers with an ace hidden in your sleeve, fooling even the magic gods themselves
