Ecaflip's Card Throw

You imbue a card with random magical properties then throw it at a creature or object within range. Make a ranged spell attack against the target. For each target, roll a d6 to determine the color of the card. On a hit, a target is hit by a card of one of the following colors, which each have a unique effect. 

1. Red: The card lights on fire and burns the caster's hand while being thrown, the caster takes 1 fire damage, then the target takes 1d8 fire damage. 
2. Green: The target takes 1d6 acid damage, and it can't regain hit points until the start of your next turn.
3. Yellow: The target takes 1d6 lightning damage and it can't take reactions until the start of its next turn.
4. Blue: The target takes 1d6 cold damage and its speed is reduced by 10 feet until the start of your next turn.
5. Purple: The target takes 1d6 psychic damage and it has disadvantage on the next weapon attack roll it makes before the end of its next turn.
6. White: The target takes 1d12 force damage. 

The spell imbues more cards when you reach higher levels: two cards at 5th level, three cards at 11th level, and four cards at 17th level. You can direct the cards at the same target or at different ones. Make a separate attack roll for each card.
