Nether Shepherd

When Nether Shepherd enters the battlefield, if
it was foretold, you may put up to X cards you
own with foretell from exile into your graveyard.
You may activate foretell abilities of permanent
cards in your graveyard if you pay an additional
2 life to activate them. Spells foretold this way
gain "If this permanent would be put into a graveyard, exile it instead."
