Cosmic Intervention

Because exiling a card with foretell from your hand is a special action, you can do so any time you have priority during your turn, including in response to spells and abilities. Once you announce you’re taking the action, no other player can respond by trying to remove the card from your hand.

If you’re casting a foretold card from exile for its foretell cost, you can’t choose to cast it for any other alternative costs. You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, those must be paid to cast the spell.

Each permanent that is exiled instead of being put into a graveyard from the battlefield creates its own triggered ability to return itself. Those abilities all trigger at the beginning of the next end step, and you can choose the order in which those abilities will go on the stack. The cards will be returned to the battlefield one at a time as those abilities resolve.
