Taii Wakeen, Perfect Shot

Legendary Creature — Human Mercenary

Whenever a source you control deals noncombat damage to a creature equal to that creature's toughness, draw a card. {X}, {T}: If a source you control would deal noncombat damage to a permanent or player this turn, it deals that much damage plus X instead.
