The Knight of Pentacles, in this reading, represents the nature of the situation. This card indicates a hero who is trying to achieve something important, which is not yet fully under his control. There's an opportunity here, but there's also a certain degree of uncertainty. Magician Lucas may be aware of the risks he is about to take with Lorenzo and therefore the nature of the situation may be partly uncertain.

The Lovers are the cause of the problem. This card indicates that there is a strong bond between Mage Lucas and Lorenzo. There may be a relationship of trust between them or an agreement that they must abide by. This means that Lucas needs to think carefully before trusting Lorenzo, as their relationships are very important to both of them.

Finally, the Three of Pentacles indicates the solution to the problem. This card suggests that Lucas should consider all factors before deciding whether to trust Lorenzo or not. He should think carefully about what the possible outcomes of his decision will be and whether it is worth taking the risk.

In conclusion, based on the interpretations of the three tarot cards, it seems that Lucas should carefully evaluate before trusting Lorenzo in this deal. While there may be attractive opportunities to consider, there are also risks to consider and it is important to be cautious before making a final decision. Therefore, the answer to the question is: No, I don't see any risks if I decide to trust Lorenzo in this deal.
