{isochron scepter} + {noxious revival}
With any miracle card
Idea is you cast your miracle then put it onto the top of your library using noxious revival. At the next turn you miracle it then repeat the process. Long I know but still quite easy to do :)
Didn't realise it exiled itself :( so on another note any other miracle card that you want to use again you can use {noxious revival} + {isochron scepter}
Use curly brackets to link stuff like {Temporal Mastery} to know that the card is exiled when it resolves. Maybe stick a {Runic Repetition} on that scepter.
Edit: no, that doesn't work. Dang.
