Tapping Auras are a hassle.

Besides the fact that enchantments shouldn't tap anyway, tapping things you attach to creatures is the worst idea, since most people just tap them along with the creatures.

I just noticed that Aether Revolt did remove all equipments when it went with improvise.

Strangely enough, I had placed some though of how something like Gloomweaving or Weary of the World could be non-practical with chant, yet I somehow overlooked this. I certainly have to think this design (and Auras in general in this set) through. Considering I have the (((Guests of the Gods))) design which is (also) lacking, I could have it be the common chanter instead.

Oh, and about "enchantments shouldn't tap", I added a longsome section about it in the chant's mechanic description. Hopefully it makes some sense.

It was one of the possible future directions that Magic explored in Future Sight, with things like Second Wind and Flowstone Embrace. "When playing with chant cards, you remember not to tap the aura along with the creature" seems a reasonable principle; comparable to "When playing with devotion cards, you remember to count the devotion from the auras you put on opponents' cards" like Armament of Nyx, Pin to the Earth, Viper's Kiss; or "When playing with soulbond cards, you remember to leave the creatures lined up alongside their pair", or "When playing with miracle cards, you carefully look at each card as you draw it before putting it into your hand".

The miracle example in particular demonstrates that this is a risky area, but not unexplorable.

The wording wants to tweak slightly. You want the activated ability to have chant, in the same way that spells have storm. You don't want chant to be a keyword action like scry or investigate, you want it to be an ability that triggers when you activate the ability like storm or replicate. So rather than

> : Enchanted creature gets +1/+2 until end of turn, then chant (Your enchantments can enhance this effect. Copy this effect for each enchantment you tap in response.).

I'd write it as

> : Enchanted creature gets +1/+2 until end of turn. Chant (Your enchantments can enhance this effect. When you activate this ability, copy it for each enchantment you tap [in response].)

The original chant did interact with stuff like Flowstone Embrace though it had some notable issues.

Chant (To chant, copy an ability of an enchantment you control with only in its activation cost.)

Unlike with miracles, where "backtracking" just doesn't work since you can't reasonable verify if you did indeed drew that card just now if you miss the window, with chant you can reasonable notice that "Hold on, I didn't 'really' tap this aura did I?" Also, "When playing with devotion cards, you realize that tokens don't count toward your devotion."

So yes, like I realized before, those "things to watch out for" in this environment would be "Look out for duplicate distinguished cards" and "What's the # of untapped enchantments a player controls?"

Yeah, I would buy this explanation. I don't know if it really justifies this card when it could be rather easily avoided. auras are kinda okay since they aren't one of the chant colors. The aura affects opponents' creatures and in a way that likely stops them from attacking (becoming tapped). This is rather problematic, though if you at least realize it's the aura that taps and not the creature, it should be rather clear that you should kinda keep note of this card's untapped status. I'll have to see what I do with this.

About chant wording, I kinda get what you are saying but is there any precedent at all for an (activated) ability to have an (keyword) ability of its own? That sounds pretty crazy to me. Plus around half of the chanting sources are spells and not abilities and would then require a slightly different wording for spells and abilities (stuff like Symphony of Designs and (((Song of Wizardry)))).

Here are some variations with "repeat this process" though I don't know if I would go with them being action, pseudo or actual keyword abilities:

> "(effect), then you may tap an untapped enchantment you control. If you do, repeat this process."

> "(effect). You may repeat this process any number of times by tapping an untapped enchantment you control each time."

Hmm. That does complicate things a tiny bit, but I still think it'd be better as a separate trigger to work like storm. I think it'd be legitimate for Chant to have slightly varying reminder text on activated abilities and spells, saying "When you activate this ability" vs "When you cast this spell", but otherwise work identically. (Other mechanics with variable reminder text: suspend had three variations - "it gains haste" only appeared on creatures, and "you may" only appeared on spells that also had regular mana costs. Graft and similar mechanics usually say "This creature" but vary when they're on noncreature cards like Llanowar Reborn. Amplify and embalm call out the affected creature types by name - Aven Warhawk, Anointer Priest. Sunburst is just two vaguely similar mechanics with the same name. I also have two different reminder texts on my Geass mechanic.)
