Enrage

Enrage is a triggered ability word introduced in Ixalan as the signature mechanic for the Dinosaurs of the Sun Empire. It was also featured in Rivals of Ixalan and Commander 2019.

Description
Enrage gives an advantageous effect when the creature with the ability is dealt damage. It appears in red, white and green.

Rulings

 * If multiple sources deal damage to a creature with an enrage ability at the same time, most likely because multiple creatures blocked that creature, the enrage ability triggers only once.
 * If lethal damage is dealt to a creature with an enrage ability, that ability triggers. The creature with that enrage ability leaves the battlefield before that ability resolves, so it won't be affected by the resolving ability.

Trivia

 * Fungusaur, from Alpha, functionally has enrage. With the release of Ixalan, it was officially given the Dinosaur creature type.
 * Seven other creatures functionally have Enrage printed after the release of Ixalan: Hungering Hydra, Truefire Captain, Sporeweb Weaver, Brash Taunter, Spiteful Sliver, Body of Knowledge, and Flumph.
 * Enrage was originally planned as the Gruul guild mechanic for Ravnica Allegiance, but was taken by Ixalan (The rule in R&D is that earlier sets trump later sets for mechanics).
