Well Xixo saw Satellite's Big Spell Dragon Priest (http://www.hearthpwn.com/decks/1001145-satellites-tempo-big-spell-priest-top-3-legend) and decided to bring it to Seat Story VIII as well as Big Spell Hunter! And he won the event, with priest going 3-1 vs Neirea and this hunter picking up with final win vs aggro druid.
Basic plan with this deck:
1. Play minions for tempo. Fight for board dominance first, then send the extra to face.
2. If lethal remains out of reach, control the midgame with Eaglehorn Bow, Houndmaster, and [card]Cobalt Scalebane[/card].
3. As early as possible, drop Spiteful Summoner for a free 9 cost minion and a devastating board swing!
4. Pile on with your [card]Corridor Creeper[/card]. Once cheap enough it has a great combo with Tundra Rhino!
5. Leverage your big spells further with [card]Grand Archivist[/card] who will summon 3 helpful beasts including a taunt!
Basic mulligan strategy:
Always keep Alleycat, Dire Mole, Candleshot.
With coin or any 1 drop keep Crackling Razormaw, Corridor Creeper, and Southsea Captain.
Consider keeping Southsea Deckhand with any weapon
