Besmirch is an example of goad, a new mechanic. Goad makes a creature attack someone other then you as soon as possible. It seems like a slightly underwhelming mechanic, because there’s not much you can do with it.
Keeper of Keys is a good example of monarch. Being the monarch is an advantage and a disadvantage. It allows you to draw an extra card per turn, but it makes you a target for everyone else who wants to be the monarch.
This is an example of the mechanic Melee. It encourages attacking different players. It doesn’t seem extremely powerful or overwhelming, but it’s pretty nice.
