Aces High

This ordinary-looking deck of 52 playing cards stores a variety of spells and confers the ability for its attuned wielder to cast them as if they are on the wielder's spell list. When attuning to the deck, the wielder chooses whether to use their Intelligence, Wisdom or Charisma modifier to determine spell attack bonus and save DC.

To use this item, the player must have a modern deck of playing cards on hand. When this magic item calls for the character revealing a card, shuffling the deck, etc: the player does so with their deck.

As a Bonus Action, the deck's wielder may reveal the topmost card of the deck to determine what spell is available. As an Action, the wielder may then cast the spell correlating to the revealed card according to the following table. A card need not be used immediately after being revealed.

Suit: Hears

• Pip (number) cards: Light
• Face cards: Wardaway
• Ace: Blindness/Deafness

Suit: Diamonds

• Pip cards: Sword Burst
• Face cards: Color Spray
• Ace: Heat Metal

Suit: Clubs

• Pip cards: Thunderclap
• Face cards: Thunder Wave
• Ace: Shatter

Suit: Spades

• Pip cards: Sorcerous Burst
• Face cards: Ice Knife
• Ace: Scorching Ray

Once the spell has been cast, the card is added to a discard pile. Cards in the discard pile are mundane until the deck has been reshuffled. Regardless of how many cards are in the discard pile, the deck can be reshuffled during a Short or Long Rest. The deck may only be shuffled this way once every 24 hours.

If any card is lost, destroyed or otherwise separated from the deck, the deck becomes mundane.

Mulligan: If the attuned wielder has a Feature or Feat that allows them to manipulate the odds of success by re-rolling or otherwise changing the rolled result on a D20 (for example: Inspiration, Lucky, Indomitable, Portent): after a card is revealed, they may expend a use of the feature to place the card on the bottom of the deck and reveal the next card.

Aces High, Deuces Wild: Rumor has it there is a Very Rare version of this deck where drawing a 2 allows the wielder to choose any spell from the list above.

Notes: character who chooses to use Int, Wis or Cha for attack bonus and save DC.
