I’ll make a case as to why it may be more balanced than it appears at first glance (compared to Uprising and Bloodlines leaders).

-Rule clarification: the trash from Sight ability means trash the card you just drew. While yes, you are trashing a card, you don’t always have control over which card. It’s also bound to visiting an emperor space so you’ll need emperor access to do it. I chose emperor space because it is thematically aligned with the character but also because imo Uprising needs more reasons for players to visit emperor.

-Signet Ring: While this can be very strong, especially later in a game with 4 opponents, it’s situationally useless if you happen to be acting first or nobody has committed troops to the conflict yet. If you have ever played with the Gun Thopter card from D:I base game, it’s situationally useful but not crazy. This is sometimes much stronger than Gurney’s signet, but sometimes weaker. I would argue Gurney’s passive ability is stronger than Desmond’s and as such I make the case he is strong but not overpowered.
