Skull Raid

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.

The opponent must discard two cards if they have two or more cards in their hand. If they have only one card in hand, they’ll discard that card and you’ll draw a card. If they have no cards in hand, they can’t discard any, so you’ll draw two cards.

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.
