The declared hand is the hand that remains after the discard. A card cannot be outside the hand for the count and inside it for completing a sequence. This is where a fourteen-card preview can be misleading: it shows more material than the final hand is allowed to retain.
Use a thirteen-card exercise requiring at least two sequences, including a pure sequence. A draw adds one card and a discard removes one. Compare the two final inventories below; the same draw can leave different groups depending on which card is removed.
Start one card short
Take these thirteen cards, without any designated wild rank:
4♣ 5♣ 6♠ / 9♥ 10♥ J♥ / 7♠ 7♥ 7♦ / A♦ 2♦ 3♦ 4♦
The hearts and diamonds form natural sequences, and the sevens form a set. The first row is not a sequence: 6♠ is the wrong suit beside 4♣ and 5♣. The hand contains thirteen cards, but not a complete arrangement. This example allows an ace at the low end of A–2–3–4.
Now a specified draw from the closed deck adds 6♣. There are fourteen physical cards: the original thirteen plus the club six. Both sixes are visible in the working hand, but only thirteen cards may remain after the discard.
Discard the spade six
Remove 6♠ and place 6♣ with 4♣ and 5♣. The final groups are:
4♣ 5♣ 6♣ / 9♥ 10♥ J♥ / 7♠ 7♥ 7♦ / A♦ 2♦ 3♦ 4♦
The count is 3 + 3 + 3 + 4 = 13. All three sequences are natural, the sevens form a valid set, and no card is left over. Under the stated conditions, the arrangement is complete.
Discard the six of clubs
If the newly drawn 6♣ is removed instead, the original incomplete hand returns. The club six cannot still be counted beside 4♣ and 5♣: it has left the hand. The surviving 6♠ does not take its place in a club sequence. There are thirteen cards, but the same suit mismatch remains.
This is why “thirteen cards remain” and “the declaration is valid” are different conclusions. Correct count is necessary in this exercise; correct grouping is necessary too.
Read the settled state, not an animation
A moving card or an old preview may still appear near its former group. For a review, write the accepted draw, the accepted discard and the final inventory. The final inventory resolves membership more clearly than where a card happened to be during an animation.
Restrictions on returning a card taken from an open pile are a separate question. The example specifies a closed-deck draw and should not be copied unchanged into an open-pile situation. Likewise, no penalty amount follows from the invalid arrangement alone. This lesson establishes what the two final hands contain, and which one meets the stated grouping rule.
