{seraph sanctuary}
{restoration angel}
{fiend hunter} x2
Have 1 or a few seraph aanctuarys down and flash out resto angel before opponent ends turn when time is right
On your turn play both fiend hunters to start an infinite loop of exiling them and with seraph sanctuary you gain life every time angel enters play
Fiend Hunter juggle combos have been posted many times on these forums. The only difference I see with this one is that you're using the flavor of angels to gain life instead of a {Soul Warden} or similar with 3 Hunters.
Edit: Ah I guess yours is still standard.
Yeah and standard decks are where it's at IMO, actually useable =P
