Princess Zelda, Fair Lady

Lifelink, protection from black

Peaceful heartland (When Princess Zelda enters the
battlefield, put all Land cards from your library into
one face-down pile and the rest cards into another.
Whenever a rule, spell or ability targets any number
of cards in your library, you may use cards from
both/any of those piles of your choice to comply it.
When Princess Zelda leaves the battlefield, shuffle
one pile into another. It becomes your library)
