There are loads to trawl from in the Spellbook section! I'd advise an Aggro vs. Control match-up
Below are 2 contrasting classic strategy builds you should be able to build with 1 Core Set
(You may need to proxy a few Teleports and other Utility spells used in both books)
Straywood Beastmaster Aggro (very aggressive but little mana boost)
http://forum.arcanewonders.com/index.php?topic=13107.msg23953#msg23953Air Wizard Mana Denial Control (cerebral control build with an Enchantment Transfusion Win Condition)
http://forum.arcanewonders.com/index.php?topic=13111.msg24123#msg24123Matches should go something like this:
Beastmaster aggressively attacks from the start
Wizard looks doomed unless played well (Armour + Voltaric Shield, Hydra guard etc)
If the Wizard survives, his mana advantage will start to pay off as the Beastmaster runs out of steam
The Wizard then takes Control and pushes for the win, though a careless mistake could snatch defeat
Sometimes the games will be short as the Beastmaster's all-out aggression wins
Sometimes the games will be long as the Wizard "slowly turns the screw" and wins
Playing Wizard is definitely more challenging but also more rewarding when he wins
Other than that, for a lesson in how to build a book, read piousflea's Bashcon Beatdown thread (Warlock)
The decision tree early game planning is crucial when strategising your own book and it's a very solid build
