Servant of Tymaret

Inspired abilities trigger no matter how the creature becomes untapped: by the turn-based action at the beginning of the untap step or by a spell or ability.

If the inspired ability includes an optional cost, you decide whether to pay that cost as the ability resolves. You can do this even if the creature leaves the battlefield in response to the ability.

Inspired abilities don’t trigger when the creature enters the battlefield.

A creature taps when its regeneration shield is used, not when the shield is created. Notably, you won’t be able to use Servant of Tymaret’s last ability to tap it so that its inspired ability will trigger unless Servant of Tymaret would be destroyed.

If an inspired ability triggers during your untap step, the ability will be put on the stack at the beginning of your upkeep. If the ability creates one or more token creatures, those creatures won’t be able to attack that turn (unless they gain haste).
