Thornbow Farseer

Vigor (Remove damage from this creature as steps and phases end, rather than at the end of the turn. At the beginning of your upkeep, you may remove a -1/-1 counter from this creature.)
Whenever Thornbow Farseer blocks a creature with Flying, it gains First Strike until end of turn.
The Farseers of the Thornbow tribe are empowered by the spirit of the Eagle. They never miss their target, no matter how small, how fast, or how far away.
