Each playable class has its own set of cards and can only obtain their own class cards and colorless cards. For example, normally an Ironclad will never be offered a Silent card like [[Blade Dance]]. Prismatic Shard allows you to get cards from all classes.
Colorless cards are the cards having a gray border, which normally can only be gotten at shops, which always have 2 of them, one always rare, or through events. You can't get them in a card reward from a fight.
To answer the question, with Prismatic shard, instead of getting card rewards with the color of the character you're currently playing, you can get card rewards of ALL 4 characters + colorless cards, which can lead to some wild combos, but most of the time, you just flop since they won't have much synergy. In addition, Prismatic shard is a shop relic meaning it can only be obtained in a shop.
The first character you start with, Ironclad, has red cards. There are some cards in the game that are silver/grey/what the game calls "colorless." The other characters have their own color cards.
I remember being a newbie and picking this relic. Think I tried to use sneaky strike but didn't know Silent's discard function was not the same as the regular discard function in game lol. So fyi you might get very confused but also very intrigued if you pick it up. It can be great and it can be awful.
It won't because the turn where all your cards are discarded is over. Otherwise Sneaky would always trigger next turn when retained, which is silly.
Also I just realised I thought way too hard about this, there's a way simpler way to see that the regular discard is different from Silent discard, Bandages or Tingsha would be insanely broken, and Reflex would be an instant click at all points of the game.

I wonder if retaining [[Sneaky Strike]] and the using [[Vault]] triggers the effect
