Abimelek, King of Gerar

When Abimelek enters the battlefield, search
your library for a card named Sarah, Mother of Nations & put it onto the battlefield under your control. Then shuffle your library.
At the beginning of your upkeep, if you control
Sarah, you lose 2 life unless you sacrifice it.
If you sacrificed Sarah this way, return
it to the battlefield under its owner's control at
the beginning of the next end step.
