I'm curious about Prairie Stream and Sunken Hollow. How have those been in your experience? It seems like they could either be great or total duds.

They aren't great, but the deck is really greedy on blue and black. I just like having the option to fetch a Hollow/Stream when I don't need the mana, such as on the end of an opponent's turn, and still leave the option to grab 2 untapped duals with my other fetches.

I might probably replace the Stream with a basic Swamp since stax is slowly coming back to my meta, but the ability to fetch 3 UB duals saved me a few times, so I'm more inclined to keep the Hollow.

Seriously cool idea. Is this still a viable deck if I can't afford the candlestick, seal, and mana drain?

Seal is optional. You can easily replace it with Thirst for Knowledge, Opt, Peek or Intuition. Mana Drain can also be replaced with Counterspell with no significant impact on the gameplan.

Candle is crucial, and while the deck can work without candle, it makes your Shimmer Myr lines a lot less reliable.

How's Mind's Desire working? What was replaced?

Also Intuition and Cyclonic? Very cool changes.

It seems like a shift away from Shimmer Zur and towards a spell-based storm build.
