Snake Umbra

If a permanent enchanted with an Aura that has totem armor has indestructible, lethal damage and effects that try to destroy it simply have no effect. Totem armor won’t do anything because it won’t have to.

If a permanent you control is enchanted with multiple Auras that have totem 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 spell or ability (such as Akroma’s Vengeance) would destroy both an Aura with totem armor and the permanent it’s enchanting at the same time, totem 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.

If a spell or ability says that it would “destroy” a permanent enchanted with an Aura that has totem armor, that spell or ability is what causes the Aura to be destroyed instead. Totem 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 totem armor, the game rules regarding lethal damage cause the Aura to be destroyed, not that spell or ability.

Totem armor’s effect is mandatory. If the enchanted permanent would be destroyed, you must remove all damage from it (if it has any) and destroy the Aura that has totem armor instead.

Snake Umbra grants the triggered ability to the creature. It triggers whenever the enchanted creature deals damage to an opponent of its controller (who is not necessarily an opponent of the Aura’s controller). In other words, if your Snake Umbra winds up enchanting your opponent’s creature, that opponent will draw a card whenever that creature damages you.
