Here is a fun Mage deck using 5+mana spells to take advantage of Dragon's Fury & Grand Archivist.

Cabalist's Tome, Dragon's Fury, Blizzard and Flamestrike are the only spells so playing a turn-8 Archivist almost guarantees a board swing. The Dragon's Fury also cannot "miss" as everything costs 5-7 mana. Massive AoEs only get you so far so the deck calls upon three big game-enders in the form of Medivh, the Guardian, Dragoncaller Alanna and Frost Lich Jaina. At least one copy of Arcane Artificer is important and the deck also includes a couple tech choices with Golakka Crawler & Gluttonous Ooze.
