Kua Fu, the Sun Chaser

When Kua Fu, the Sun Chaser enters the battlefield, you may choose to destroy target
swamp and/or island.
When Kua Fu, the Sun Chaser leaves the battlefield, search your library for a basic forest
and put it into play tapped. Shuffle your
library afterwards.
Kua Fu wanted to prove himself by chasing the Sun,
and died of thirst in the process.
