Magic - The Gathering - Battlemage
Whatever wizard you choose, always visit the Tome Builder
to reconfigure your available spells from all those available
in the game. This gives you a say in your wizard's casting
strategies later during the duel.
Always provide yourself with a 33-33-33 mix of cards in lands,
summoned creature spells, and other spells.
Don't worry much in the early game about conquering provinces.
You need spells first, and the less your lands touch upon the
other wizards', the better. Whenever they attack a land of yours,
you'll duel them.
Before attacking a province, study its text. It will sometimes
contain clues about the inhabitants' attitudes toward various
wizards, which you can turn to your advantage.
