I have a card game which has 7 type of unique cards for a total of 21. The structure of the deck is the following:
- card A: 2x
- card B: 2x
- card C: 2x
- card D: 3x
- card E: 3x
- card F: 4x
- card G: 5x
At the start of the game the deck is shuffled and 1 card is discarded. Then, the 2 players are dealt 6 cards each. Then, the player who starts draws a card.
I am looking for each unique combinations of cards player 1 can have in their hands after they draw a card.
