Aggressive Trendsetting is to asset spam what Stegodon MK IV is to glacier. A tax on the runner.
This agenda is made for Poétrï Luxury Brands: All the Rage, because it tax the runner from trashing cards installed by the identity. But in my opinion, it shines best with Thule Subsea: Safety Below to form a kind of near click prison. If the runner score an agenda, they are taxed with 1 and 2. And if the runner runs an asset, they are taxed the trash cost of the asset and 1. If you add cards like Active Policing, Mr. Hendrik, Pulse and Hypoxia, the runner will be easily be taxed 1 nearly each turn on average.
The issue of the agenda is the same as Stegodon MK IV : it is a 3-1 agenda, the least efficient to score and it need to be scored early to have a real impact. Which incentive the corp to have 3x of Aggressive Trendsetting. Forcing the corp to have more agendas. 2x is usually enough though.
Depending on the board state and how fast can the runner setup, this agenda can be useless or game winning. In every case, it will be impactful.
Art is nice and very evocative of the name of the agenda, going well with the quote. And the effect is hinted at by the whole design. Well done.
