NOTE: You can't change the targets for the copies.

At the end of the chant reminder text this also would be included:

> Mana abilities can’t be targeted.

Given how powerful Rings of Brighthearth is, I feel like there should be a very high mana cost to that ability, this artifact, or both. It definitely feels mythic, though, but copying certain triggered abilities like those from Heavenly Host or Taint seems really really strong, especially because you can chant those cards to get 3x the triggers.

Oddly, the more I think about Chant mechanically, why isn't it something like:

Chant - , Tap any number of untapped enchantments you control: Copy target or activated ability. You may choose new targets for the copy. Repeat this process for each other enchantment you tapped this way.

I guess that could work, but with it most of the text on these chant cards would be about explaining chant, not the effect that's being chanted. IMO the current variation where that is relegated to the reminder text is much more grokkable. Also, I'm not 100 % how that would work for cards like Symphony of Designs that are not permanents.

While that's true, the reminder text you currently have is taking up a lot of space as well and IMO reminder text is more distracting than regular text, because the italics draws your attention away from the effect. Both regular text behind a pseudokeyword like Morbid or Battalion and reminder text don't count towards complexity when factoring NWO.

There's also this version (both permanent and nonpermanent versions) that I came up with - it's a little more labor intensive, but it should provide relatively the same effect.

Legendart Artifact Enchantment Chant - : Copy target activated or triggered ability. You may choose new targets for the copy. Then, you may tap an untapped enchantment you control. If you do, repeat this process.

Sorcery Chant - Draw a card. Then, you may tap an untapped enchantment you control. If you do, repeat this process.

With Symphony of Designs, the difference is that you'd draw the cards one by one in sequence with the effect, so you could choose when to stop chanting if you draw the card you want, all in one trigger. With the way your current version works, what happens is:

>Draw a card. >Decide how many enchantments I want to tap and tap them. Copies, if any, go on the stack. >Draw the rest of the cards in separate triggers. Option to chant again for each trigger.

Not trying to be super adamant about any of this here - just offering some other options for the effect that could work the same way and (maybe?) take up less space on the card and on the stack.

> IMO reminder text is more distracting than regular text

That's a really confusing opinion. I just think of it as "If I'm sure what this card does, I can happily ignore it". Personally, I really like reminder texts - even when they aren't really required.
Suspend has two variables which is also kind of bad and cascade... yeah, that's just too long - even after they cut those "in any order" and "CMC" parts out. Looking at Yidris, Maelstrom Wielder for example it can be seen that more than half of that card's text is the cascade reminder - five lines with small font - crazy! For this card (silmarils) I could cut that reminder text into just "Copy this effect for each enchantment you tap in response" - currently it also has that "mana abilities can't be targeted" specifically for this card.

The two implementations take around the same amount of text with reminder text (I tested that immediately), but there are multiple things that bother me about the version without the reminder. In uncommon+ cards I can't cut any of that text. Plus, the reason/payoff as to why to tap enchantments comes after the effect. If the text changes slightly from card to card, you have to go through the whole text to make it sure it functions similarly. As for the "repeat this process" version, I had to read that couple of times to really notice that you can do it any number of times - it really reads at first hand like you can only tap one an untapped enchantment once.

IMO the "your enchantments can enhance this effect" plus "copy... for each enchantment you tap" is doing a lot of work here when it comes to understanding what the card does.

I appreciate the suggestions greatly - while I think the current version is the best of the options I've seen so far, it isn't exactly ideal.

Change text to "copy another target ability" so that way you don't target itself.

I'm pretty certain you can't use ability to target itself. At least here, when choosing the target for the ability, the ability itself hasn't been activated yet, so you can't choose it. That and I doubt many will even think of doing that since it's so backwards.

The issue would be effects that change targets (though in this case it would be more weird than game breaking, I suppose), but spells cannot target themselves, so while I have never checked it's reasonable to assume there is a similar rule in place for activated abilities/objects on the stack in general.

That said does the single word cost you much just to shut down any imaginary loopholes?

Well... I might as well add it... I'll get to that once I can update the MSE file.
