Enchantress
The Enchantress archetype can be built in many ways but the foundation of Verduran Enchantress, Wild Growth, Fastbond and Sylvan Library usually stays the same. Verduran Enchantress is of course the engine of the deck as it lets you draw a whole bunch of cards if it stays in play. The cards you draw helps you build up a lot of mana which is later used to win the game in some way.
One classic wincon is to just Fireball your opponent to death but as 21 mana could be hard to reach the deck often use the combo Mirror Universe and Sylvan Library. Pay a bunch of life to draw a couple of cards and then change your life totals so the opponent becomes easier to finish of.
