Kamen Rider: Skyrider

Flying, Lifelink
When Kamen Rider: Skyrider enters the battlefield, search your library for a Plains, put
it on to the battlefield then shuffle you library.
{3}{w}: Kamen Rider: Skyrider loses flying and
gets +X/+X until end of turn, where x is the
number of Plains you control. Activate this
ability only anytime you could cast a sorcery.
