Santiago: Solution

To solve the puzzle, the first four cards in each row specify a letter within one of the words CLUBS, DIAMONDS, HEARTS or SPADES. For example, 1♣ = C, 2♣ = L, 3♣ = U, etc. This gives you a four letter word which applies to the value of the fifth card. In the first row below, CORE 3 says to take the core (middle) letter of THREE, or R.

A♣ 5♦ 4♥ 2♥ 3♥ CORE 3   R
5♠ 6♦ 4♠ A♠ 8♠ ENDS 8   ET
8♦ 2♥ 4♦ 2♦ 8♣ SEMI 4   UR
2♣ 3♥ 6♥ 5♥ Q♥ LAST QUEEN   N
4♥ 5♠ 5♣ 5♥ K♦ REST KING   ING

Reading down the last column above gives you the answer: RETURNING
