You may exert Anep as it attacks. When you do, exile the top two cards of your library. Until the end of your next turn, you may play those cards. (An exerted creature won't untap during your next untap step.)

4 rulings from Wizards of the Coast
- 8 November 2024You can exert Anep as you declare it as an attacking creature. You can't do so later in combat, and creatures put onto the battlefield attacking can't be exerted. Any abilities that trigger on exerting an attacking creature will resolve before blockers are declared.
- 8 November 2024If an exerted permanent is already untapped during your next untap step (most likely because an effect untapped it), exert's effect preventing it from untapping expires without having done anything.
- 8 November 2024You pay all costs and follow all timing rules for cards played with the permission granted by the ability that triggers when you exert Anep. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty.
- 8 November 2024If you gain control of another player's permanent until end of turn and exert it, and then that player regains control of it, it will untap during that player's untap step.
