Dies to Removal

What I love about Zedruu, is she can make jank cards useable.

Have you ever considered or tried Archmage Ascension?
I know it takes a few turns to get going, but drawing isn't exactly hard for Zedruu.
If you have Atlas going, tapping on other turns, you get there in as little as three.
Normally I'd never even look at that card, but here..
If it were ever useful, this would be the time?

More abstractly, this deck feels like it wants to be able to shuffle things back in more consistently.
After you cast Enduring Ideal, if they solidify their defenses, it can be harder to crack.
I'm specifically thinking if Mistveil Plains got axed.
Are you having to wait to draw Petrified Field or Ulamog?

Also, why no Homeward Path?
Is there never a time you want something back?
