Wait, how would Sombra be Gluttony?  
He does not once show any form of ‘hunger’ per se.

I actually think Sunset Shimmer would be greed, Sombra Gluttony, and Tirek Wrath.

@The_Mungoman  
No. that’s why I’m on this image website.

@Pryson the second  
Depends on how they portray him.

So if Grogar returns, he’ll be wrath, right?

Now we need a wrath and a sloth, and then we will have all seven Homonculi.

I’ll take Smooze for Sloth and Grogar for Wrath.

The Gallifreyans were actually big green wobbly pieces of jelly.  
They all just had plastic surgery. At the same time.
 
YOUR MOVE, CHUMP

@The_Mungoman Azula, The Boulder, and Jun share a great great hermaphroditic grandpa  
There. Your move, ponifig!

@Princess Luna  
Well, yes, but Discord has shown pride most strongly, condescendingly talking down on others, as well as toying with others emotions and relationships for his own amusement.
 
Obviously Chrysalis fed on love not lust, that was obvious. I just thought she fit into the “Lust” category, because of the whole love motif, as well as her ‘devouring’ love, but giving none in return.
 
I chose Tirek for gluttony due to the used imagery, as well as the fact that he wanted to keep ‘eating’ magical energy until there was none left.
 
“sometimes overanalysis makes you see things that aren’t there”  
Really? Really? Are you being serious? You are a moderator of a brony site. Overanalysis and crazy headcanons are what we do, even moreso than many other fandoms. You should know that.  
I am aware of the fact that many of these sins are interchangeable (due to all villains being, well, evil), but this is just a little idea of mine, nothing truly impactful.

@Princess Luna  
I disagree with a few things there, but mostly the idea that the ponies don’t need their magic. From everything we’ve seen, it sure looks like they can’t get by without it. They’d have no seasonal changes, no weather control, no magical agricultural advantage, and most noticeable, no day and night cycle.

Nightmare Moon, Tirek, and Chrysails also failed due to pride; Sombra is, so far, the only villain who hasn’t fallen due to their pride giving the heroes an opportunity.
 
Chrysalis was eating love, not lust. These are extremely different things (lust isn’t even necessarily sexual, it can be an intense desire for anything), especially in the context of sins (Christianity’s moral stance on love and lust are literally polar opposites).
 
Also, gluttony is something Chrysalis is far more guilty of than Tirek. Gluttony is literally desiring food to the point of taking it away from those who need it. Ponies don’t actually need their magic, but they do need their love. Tirek was also only taking their magic as a means to an end (the end being power), whereas for Chrysalis the thing she was eating was the end.
 
tl;dr:sometimes overanalysis makes you see things that aren’t there, and seven deadly sins analogies is one of the most common pitfalls.

I’d say that Sunset’s vice was more pride than envy, although the two are related.

@Millennial Dan  
Well, I dislike EqG, you like it.
 
Opinions, man, everyone’s got ’em.

Meh at the Sunset hate. It all sounds like anti-EqG bias to me, and I already know what that’s all about.

@Page Turner  
I guess. We’ll just have to wait and see.

@The_Mungoman  
Even so, I kind of doubt that we’ll be getting a Sloth-based major villain any time soon, so The dragon is a good placeholder for the sake of a complete set.

@Background Pony #9347  
…  
Do you even have eyes?

So… Trixie as Envy, then?

@Page Turner  
I was actually going more for two-parter villains, ones from either the Season openers, or the finales.

I’m Pretty sure Sunset Shimmer is also Envy, and the dragon from Dragonshy is Sloth, because the threat he posed was caused by him sleeping and they had to go wake him up.
 
Now we just need a wrath villain to complete the set.

So we need sloth and wrath.

@Itsthinking  
Doesn’t change the fact that they had little to no screen time.

@The_Mungoman  
Which is why she went to another universe to scheme and plan it out? She was thinking of the invasion plans all along.
 
@PonyPon  
You seriously overestimate the intelligence of ponies against someone who is charismatic/scary enough.
