La Llorona

Landfall — Whenever a land enters the battlefield
under your control, choose one —
•Draw a card. Then, discard a card unless a creature
card entered an opponent's graveyard this turn.
•Sacrifice a land. Search your library for a creature
card, then shuffle your library and put that card on
top of it.
"Oh! My children! Where are they?"
