Cheetah Freerunner

Dash {4}{w} (You may cast this spell for its dash cost.
If you do, it gains haste, and it's returned from the battlefield to its owner's hand at the beginning of the next end step.)
Whenever Cheetah Freerunner attacks, search your library for a plains, reveal that card, and
put it into your hand then shuffle your library
and you gain 1 life.
