This deck is insane, most of the players just forfeit when I play Fulmar with zeal. Very good even against hyper-control decks.
The idea here is to go Melusine round 1, with Messenger of the sea. That will win you round one instantly, if not just play rain and messenger as required. Then go for a long round 3. Save up rain charges for Fulmar, recall Melusine, play Fulmar then Otkell and, lastly, Bride of the sea. You can also defend round 2 easily if you loose round 1 by any chance.
You can swap Svalblod priest with Scepter of Storms. You can also try this deck with Magic Compass if you want.
EDIT:
You can play Otkell from compass (Previously I was unsure if it will work, but I have confirmed it, it works). for the extra one provision left, swap Svalblod Priest for Gremist for a purify option.
Otkell(13) => Magic Compass(12)
Svalblod Priest(5) => Gremist(6)
