Your primary plan is to play out some early attackers and then use your spells to stay on the offensive. If you have a Scroll Thief, use your spells liberally to get it through and draw more cards. Frost Breath and Master of Diversion can tap down blockers, and Show of Valor allows you to attack even if your opponent has a large creature on defense. Consider saving Claustrophobia for serious threats because it's your best way to permanently lock down a creature.
If you should find yourself on the defensive, those same spells are also great at slowing down your opponent's attacks. A good strategy in this situation is to keep attacking with your fliers while you slow the enemy down with spells and blockers. As the game goes on, you'll gain access to powerful flying creatures like Air Servant and Jace's Mindseeker. If your air force can finish off your opponent in time, you won't need to worry about his or her army! By using a variety of spells, you can keep your opponents guessing.
The Magic 2014 core set card Domestication can steal one of your opponent's creatures over to your side, and Windreader Sphinx is a great creature to close out a long game. Azorius Charm from Return to Ravnica can put a creature back on top of your opponent's library, or grant all of your creatures lifelink for a turn.
