I'm a fairly long time lurker of the design contest board, but I thought I might as well register so I could throw my hat in for this contest with a design I had already been thinking about.
Warmongering is a straightforward riff on Black Market, adding a selection of cards you can buy from "outside the game". The obvious card trait to call out to narrow down the selection for a set aside deck and to differentiate the effect from that of Black Market somewhat is Attack, which I think is great for guaranteeing that the Kingdom has opportunities for interaction. It also makes even more obvious the main draw of the Black Market effect - adding diverse terminal payload to an engine, for which Attacks are often perfect.
This much text is an awful lot for a landscape, but I think that might be forgivable for what is ultimately a relatively straightforward concept without any of Black Market's Treasures in the Action Phase and Buying without Buys fiddliness. It also wouldn't truly be a feasable card for a Dominion expansion given its requirements of your collection, but I can maybe imagine it as a promo. If I am to admit one major potential balance-related flaw of this design, it's that some Attacks - chiefly Ambassador - threaten to be very swingy if offered early and exclusively to a single player, but I don't know if further complicating or nerfing the card would be worth it just to deal with that.
