Hydra Trainer rulings

2024-06-07
If 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.
2024-06-07
If 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.
2024-06-07
You can exert Hydra Trainer 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.
2024-06-07
You don't choose a target for Hydra Trainer's first ability at the time it triggers. Rather, a second "reflexive" ability triggers when you exert Hydra Trainer this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
2024-06-07
The value of X is determined only once, as the reflexive triggered ability resolves.
2024-06-07
You can always activate an ability that will cause a creature to adapt. As that ability resolves, if the creature has a +1/+1 counter on it for any reason, you simply won't put any +1/+1 counters on it.
2024-06-07
If a creature somehow loses all of its +1/+1 counters, it can adapt again and get more +1/+1 counters.

Hydra Trainer keyword rules

Adapt Rule 701.43

“Adapt N” means “If this permanent has no +1/+1 counters on it, put N +1/+1 counters on it.”

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 .)
