I was going to leave a comment about Phage-touch, but then I realized that it triggers after damage. Might want reminder text to that effect. (Still nasty with double strike, but that brings it into Johnny territory)

I've never been a fan of creatures giving abilities to creatures on a non-activatable-basis, but that's just me. This is a cool ability with cool art. I'm not sure I like it as an enchantment creature because you have so many cross-seeded cards that it may make the two archetypes ( Rebels and half-chant) blend a bit too much together.

Enchantment obviously makes sense with cards like Lady of the Sea, but at some point I decided that it also reflects flavor as well. Those Maiar are enchantments in addition to their types who are still able to change their form and haven't become 'tained' and locked into their physical manifestations. 'Walkers are an exception to this though. Lifeless Recreant also isn't an enchantment since it's actually more of a ghost rather than a Maiar spirit. This particular card is kind on the edge whether it 'should' be an enchantment or not. Mechanically I try to keep it so that enchantment creatures have at least some static/global effect that would make sense on an noncreature enchantment. Sublime Vessel kinda fails in that and this to a lesser extent as well.

Design wise there are two things that are somewhat bothersome in this card.

• Redundancy/irritation in "Whenever... attacks, it gains Whenever this deals'...
• That ability could possibly be read as "that player's life total becomes 1 UEOT" while the UEOT actually refers to the duration of the ability not to the duration of its possible effect.

I don't think reminder text is necessary. I could also go with some variation of "If this would deal combat damage to a player, instead that player's life total becomes 1" but that has its own issues.
