My personal opinion: if Eggster doesn't go an agent he's comfortable with (i.e. Yoru, or if he "mastered" some other agent"), Envy is screwed. (I think) It's better to play what you are good/helpful with than to play flex when you are useless while playing flex.

So if Eggster doesn't play Yoru here, despite the nerfs, I think there is a high chance Envy will get stomped on. I don't think he has had enough time to learn another agent yet.

That's just my opinion though ;)

Edit: If Eggster plays Yoru, I believe Envy has a decent chance of winning this.

Edit: I stand corrected.
