Extreme Focus

Whenever a spell is cast, its controller gains life equal to its converted mana cost.
Whenever a spell is countered, or cast without paying its mana cost, Extreme Focus deals damage to its owner equal to its converted mana cost.
Following can lead to a long and prosperous existence. Misuse of power cannot, and will not be tolerated. The Jeskai will teach and be taught, but wont deal with immaturity.
