Umbra armor

Umbra armor is a keyword ability that was introduced as Totem armor in Rise of the Eldrazi and returned in the Savage Auras deck of Planechase 2012, the Adaptive Enchantment deck in Commander 2018, and in Modern Horizons. If a permanent enchanted by an Aura with umbra armor would be destroyed, the Aura is destroyed instead. If that permanent is a creature, all damage is removed from that creature. In this sense, umbra armor works similarly to Regeneration. 
==Description==
In the Rise of the Eldrazi set there are 10 aura cards with umbra armor; green (4), white (3) and blue (3). In addition, the creature card <c>Umbra Mystic</c> can give the umbra armor ability to auras.
All auras with umbra armor in Rise of the Eldrazi have a two-word name, consisting of the name of an animal followed by the word 'Umbra'. The artwork of these cards (all illustrated by either Howard Lyon or Christopher Moeller) depicts a floating humanoid, surrounded by a glowing 'aura' in the color of the card and in shape of the animal the card is named after. For example, <c>Bear Umbra</c> depicts an elf surrounded by the glowing green figure of a bear, <c>Hyena Umbra</c> depicts a human surrounded by the glowing white figure of a hyena, and <c>Eel Umbra</c> depicts a merfolk surrounded by the glowing blue figure of an eel.
<c>Totem-Guide Hartebeest</c>, also from the Rise of the Eldrazi set, is a card that tutors for an aura. Although its name links it to the umbra armor auras, it can tutor for any aura card, not just ones with umbra armor.
Three new Umbras were printed in preconstructed decks; one white and the only multicolored one in Planechase 2012, and a blue one in Commander 2018. <c>Estrid, the Masked</c> also generates Aura tokens that have umbra armor. Modern Horizons brought another green Umbra, with the distinction of having a new artist (Zack Stella).
===Change from Totem armor to Umbra armor===
In 2023, R&D reviewed its stance towards Totem armor as part of a review of terms that might be considered culturally offensive. The decision was made to rename the keyword ability to "Umbra armor". This change was implied to be made for cultural reasons, as Totems are considered sacred objects or symbols that serve as an emblem of certain groups of of people. The change was implemented as part of the Oracle updates for Modern Horizons 3 in June, 2024. That set also featured the first printed card with the amended name in .
==Rules==
==Rulings==
*Umbra armor's effect is mandatory. If the enchanted permanent would be destroyed, you must remove all damage from it and destroy the Aura that has umbra armor instead.
*Umbra armor's effect is applied no matter why the enchanted permanent would be destroyed: because it's been dealt lethal damage, or because it's being affected by an effect that says to "destroy" it (such as <c>Doom Blade</c>). In either case, all damage is removed from the permanent and the Aura is destroyed instead.
*Umbra armor has no effect if the enchanted permanent is put into a graveyard for any other reason, such as if it's sacrificed, if it's legendary and another legendary permanent with the same name is on the battlefield, or if its toughness is 0 or less.
*If a permanent you control is enchanted with multiple Auras that have Umbra Armor, and the enchanted permanent would be destroyed, one of those Auras is destroyed instead—but only one of them. You choose which one because you control the enchanted permanent.
*If a creature enchanted with an Aura that has umbra armor is indestructible, lethal damage and effects that try to destroy it simply have no effect. Umbra armor won't do anything because it won't have to.
*If a creature enchanted with an Aura that has umbra armor would be destroyed by multiple state-based actions at the same time (because it's been dealt lethal damage and been dealt damage by a source with deathtouch, for example), the umbra armor's effect will replace all of them and save the creature.
*If a spell or ability (such as <c>Planar Cleansing</c>) would destroy both an Aura with umbra armor and the permanent it's enchanting at the same time, umbra armor's effect will save the enchanted permanent from being destroyed. Instead, the spell or ability will destroy the Aura in two different ways at the same time, but the result is the same as destroying it once.
*Umbra armor's effect is not regeneration. Specifically, if umbra armor's effect is applied, the enchanted permanent does not become tapped and is not removed from combat as a result. Effects that say the enchanted permanent can't be regenerated (as <c>Vendetta</c> does) won't prevent umbra armor's effect from being applied.
*Say you control a permanent enchanted with an Aura that has umbra armor, and the enchanted permanent has gained a regeneration shield. The next time it would be destroyed, you choose whether to apply the regeneration effect or the umbra armor effect. The other effect is unused and remains, in case the permanent would be destroyed again.
*Say you control a permanent enchanted with an Aura that has umbra armor, and that Aura has gained a regeneration shield. The next time the enchanted permanent would be destroyed, the Aura would be destroyed instead—but it regenerates, so nothing is destroyed at all. Alternately, if that Aura somehow becomes indestructible, the enchanted permanent is effectively indestructible as well.
*If a spell or ability says that it would "destroy" a permanent enchanted with an Aura that has umbra armor, that spell or ability causes the Aura to be destroyed instead. (This matters for cards such as <c>Karmic Justice</c>.) Umbra armor doesn't destroy the Aura; rather, it changes the effects of the spell or ability. On the other hand, if a spell or ability deals lethal damage to a creature enchanted with an Aura that has umbra armor, the game rules regarding lethal damage cause the Aura to be destroyed, not that spell or ability.
