The winds of magic are rich and varied, and none know this as well as the elven mages. Your spellbook might be a bit unwieldy (20 different tactics - yeah, I'm nuts), but Perfecting the Spell will make it easier to find the right pages in your grimoire. And the developments you're going to need for that will also help you in many other ways. Not least of these is the mysterious art of the True Mages, whose destructive magic can be channeled into power with the Gifts of Aenarion, or used to punish your enemies with Asrai Longbows. And if the enemy is discourteous enough to assemble a large fighting force, there are always the Flames of the Phoenix. The pertinent question, of course, might be where exactly in your deck they are.
