Would you care to elaborate on why that is? I would say it's easily the best piece of star wars media to come out since Disney took over, and arguably prior to that. It doesn't get overly bogged down in trying to reference or shoehorn in references to other star wars characters like parts of The Mandalorian or the sequel trilogy and it tells a compelling and emotional narrative about the path one man takes to become a dedicated member of the resistance
Right, thats likely why all of the similar cards i could find on a search were triggered abilities. But, if you go through all of the layers in order then the resulting power after 1 pass will stay that value until something else changes the game-state and causes them to recheck since the +X/+0 will have already been applied.
Since you describe it as a constant modifier rather than a triggered ability like all of the similar cards i could find i would say this sounds like a Layers deal. Layers are the order in which constant effects are applied and I personally don't know enough to say for sure, but if you start by looking up MTG Rules Layers that should be a solid starting point.
The math fun fact I remember best from college is that Charles Boole invented Boolean algebra for his doctoral thesis and his goal was to create a branch of mathematics that was useless. For those not familiar with boolean algebra it works by using logic gates with 1s and 0s to determine a final 1 or 0 state and is subsequently the basis for all modern digital computing
