Lucky fall, What are the other 2 cards?

There is insufficient information given to arrive at a unique solution by mathematical reasoning alone. The correct choice depends on the value of George's lucky number, which is not given.
The crucial piece of information in the last clue is not that the lowest card is a spade, but that there is one lowest card; in other words, the two values are different. Why did George choose this clue? Because he realized that his lucky number corresponds to two choices, the Ace-Four he's holding and Two-Two, so he chose a clue that eliminates Two-Two. This clue is only useful if the solution is Ace and Four, i.e., the clues provide no information that could be used to set any other choice apart from all other choices. It is evident that Harry's answer was not a wild guess, but the clues given were not sufficient for him to work out an answer unless the answer was Ace and Four.
