Champion of the Hareish
The buddy list mechanic exists to be a punchline, an outside-the-rules scrap of paper that pretends the game remembers what you have played. Here that gag becomes a real growth track. Because the creature enters by writing one of its own types (Rabbit or Soldier) onto the list, it seeds its own condition, and every subsequent creature that enters under your control either matches a listed type to add a counter or extends the list to widen the net for next time. The self-reinforcing loop is the whole design: the more diverse your creatures, the faster the list fills, and once it is broad nearly every creature that enters under your control triggers a counter. The check on runaway growth is that the counter only arrives on a match, and a fresh list matches almost nothing, so the payoff sits behind the bookkeeping. Strip the frame and the underlying lever is genuinely novel: a color-pie-legal white one-mana 1/1 that scales with tribal variety rather than tribal density, building up a record of listed creature types as it grows. It only functions because the buddy list is treated as a persistent object rather than a joke, which is exactly the point of building an engine on top of a gag: the gag has to hold weight for the engine to work at all.
