Deck Duelist

You rely on a deck of cards (a real deck is preferable for the best use of this subclass) to cast your spells. With inspiration taken from popular TCGs this will give you a similar vibe for a fun, chaotic and random game play experience.

Time to Duel

At 2nd level you have transcribed your spells into your deck, all spells in your deck count as prepared and outside of combat they gain the Ritual casting stipulation. Once a spell is cast you shuffle it back into your deck. At the beginning of combat you draw 6 cards and then at the beginning of each of your turns after you draw another card. Your deck is also your spellcasting focus and your spellbook.

Serum Powder

At second level, as a bonus action you may shuffle the cards currently in your hand back into the deck and draw 6 new cards.

Entwine

Starting at 6th level, when you cast a spell of first level or higher you may use your bonus action and spend a spell slot of equal level to choose a spell of that level or lower (maximum of 5th) and cast them both at the same time.

Flash

Starting at 10th level you may cast any spell in your hand as an action instead of it's regular casting time. You may do this a number of times equal to your proficiency bonus per long rest

I Choose You

Starting at 14th level you may use your action to look through your deck and find any spell and cast it immediately. You may do this once per long rest or you may take a level of exhaustion for each time you use this feature after the first.
