Trueheart Twins rulings

2017-04-18
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.
2017-04-18
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.
2017-04-18
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.
2017-04-18
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.
2017-04-18
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.

Trueheart Twins keyword rules

Exert Rule 701.39

To exert a permanent, you choose to have it not untap during your next untap step.

A permanent can be exerted even if it’s not tapped or has already been exerted in a turn. If you exert a permanent more than once before your next untap step, each effect causing it not to untap expires during the same untap step.

An object that isn’t on the battlefield can’t be exerted.

“You may exert [this creature] as it attacks” is an optional cost to attack (see rule ). Some objects with this static ability have a triggered ability that triggers “when you do” printed in the same paragraph. These abilities are linked. (See rule .)
