Now, maybe it's not AS good as the mentioned Steward of Gondor from The Lord of the Rings LCG, because the cost is certainly high on it, and Steward Basically pays for itself.
The point i think, is that if you're running a Rogue, you should be running de Luca for the action advantage it gives you. If it were in any other main faction, i would say the 6 cost is a hindrance, and the argument is stronger...but rogue certainly has the resource acceleration in their corner. . Should all Rogue decks include De Luca? it's feels like an obvious auto-include.
