Sometimes you have to fight dirty to win. Certainly, White Wizards are already known for some dirty tactics; Evasion boosting magic and stalling are strategies that don't make you well loved by your opponent, especially when mallets are involved. And surely, the combination of Wall busting Red Comet's damage and said stalling skills could easily be a problem. And the opponent's sanity being drained over time makes this exceptionally effective. But in the end, White Wizard's secret underhanded advantage comes from wielding sticks. No dog can avoid a ringout from a stick. It's definitely hopeless for Blanca.
