Entschlossene Überlebende

All cards in the Amonkhet set that let you exert a creature let you do so as you declare it as an attacking creature, as do some of the cards in the Hour of Devastation set. 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.

If an exerted creature is already untapped during your next untap step (most likely because it had vigilance or an effect untapped it), exert’s effect preventing it from untapping expires without having done anything.

If you gain control of another player’s creature until end of turn and exert it, it will untap during that player’s untap step.

Some cards have abilities that trigger whenever you exert any creature. These abilities trigger when you exert that creature or any other creature you control.

You can’t exert a creature unless an effect allows you to do so. Similar effects that “tap and freeze” a creature (such as that of Decision Paralysis) don’t exert that creature.

In a Two-Headed Giant game, Resolute Survivors’s last ability causes it to deal a total of 2 damage to the opposing team and you gain 1 life.
