Sariel, the Lone Seeker

Sariel cannot be the target of abilities.
At the beginning of your end step, if a player
controls more lands than you, you may search
your library, or graveyard for a basic land card,
and put it onto the battlefield tapped. If you
search your library this way, shuffle it afterwards
"I know I'll find what Sahaqiel is looking for. It's just
a matter of time."
