I've started work on my own little creation; the Paladin of the Lost Hour. Essentially, they don't follow the normal rules for actions (this will be explained inside the class), and get benefits and penalties from accruing "Paradox".

But, hey, they can change their initiative count by literally walking to their new place in the initiative count, can perform AoOs against things that people have done earlier in the round, and all that fun stuff...
