Dross Golem

Most Affinity creatures from this era keyed their discount off artifacts, the mechanic's namesake currency and the densest cheap permanent type in the game. This one keys off Swamps instead, which quietly relocates the whole gimmick into a mono-black shell rather than an artifact deck. The result is a body that costs five but rarely pays five: on a board with a handful of Swamps, the Golem lands for a fraction of its printed cost, and Fear means a 3/2 that most green-white and red ground stalls simply cannot stop. Whether the discount ever lines up with a payoff worth the slot is the question the card never answered cleanly, since a cheap evasive beater is the ceiling and a Swamp-light board is the floor, and both ends of that range tend to want different decks. As Affinity-for-lands experimentation, it sits alongside the small batch of cards used to test the mechanic outside artifacts proper, and it never found a home the way the artifact-affinity creatures did. What it leaves behind is a tidy illustration of why the original Affinity broke so badly: it ran on artifacts, which a fast deck floods the board with, rather than on lands, which accrue in far smaller, slower numbers. Move the same trick onto Swamps and the engine simply runs out of fuel.
