Since blue had a disproportionate number of evasion creatures compared to the other colors in a block filled with very low-powered cards, Coastal Piracy allowed the blue mage to draw multiple cards a turn in the hopes of keeping up with the white mage and his ever-growing arsenal of tutored rebels
The biggest drawback comes from its fragility
Honestly, I am slightly surprised that it has been given such a steep mana cost for its small stats, that makes me think that Blue-White might have been slightly too strong in Wizards' internal testing, so I am excited to try out this archetype
