First strike, hexproof
Whenever Narset, Enlightened Master attacks, exile the top four cards of your library. Until end of turn, you may cast noncreature spells from among those cards without paying their mana costs.
If the card has {X} in its mana cost, you must choose 0 as the value for X when casting it.

Because you're already casting the card using an alternative cost (by casting it without paying its mana cost), you can't pay any other alternative costs for the card, including casting it face down using the morph ability. You can pay additional costs, such as kicker costs. If the card has any mandatory additional costs, you must pay those.

The cards are exiled face up. Casting the noncreature cards exiled this way follows the normal rules for casting those cards. You must follow all applicable timing rules. For example, if one of the exiled cards is a sorcery card, you can cast it only during your main phase while the stack is empty.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
