Actually, I agree with this.

While a tradable Mammon would be great to have, I don't really understand the sentiment that Mammon SHOULD be tradable. It's not like the game owes us anything. There will be untradable guaranteed +2s (so far, all 5*s and below) and there will be untradable non-guanrateed +2s. All a part of the game.
