Start with A♣, 5♦ and 9♥. Draw K♠, then discard 5♦. The final hand is A♣, 9♥, K♠. Naming the cards explains what changed; saying only that the count went up and down would leave the final identities unknown.
Counts and identities answer different questions
The count follows 3 → 4 → 3. Card identities explain which three remain. A reader given only the counts cannot infer that the king replaced the five.
Include every relevant starting component
For this example, the starting hand and the specified draw are sufficient. If the question asks which card would be drawn next, the draw-pile order becomes relevant too. Do not add hidden information to the conclusion that the example never supplied.
The same method scales to a larger hand: provide the necessary inventory, identify each accepted change and reconstruct the end state. Its purpose is to show what makes a rules example checkable.
Work backwards to catch a missing transfer
From the final A♣, 9♥, K♠, remove the specified drawn K♠ and restore the discarded 5♦. The original A♣, 5♦, 9♥ returns. This reverse check helps detect an accidentally retained discard or an omitted incoming card. It works because both movements are known; it cannot reconstruct an unspecified draw from the final count alone.
Describe a different discard as a different outcome
If the same draw is followed by discarding the newly drawn K♠ instead, the final hand returns to A♣, 5♦, 9♥. The count is again three, but the result differs from the first example. Here both discards are simply specified teaching actions; the comparison shows why the name of the discarded card belongs in the explanation.
