@Lilbrudder, @Guerte: I appologize for my ruling mistake. I should have verified the comp rule before.

It seems we have a nice new tutor with Whir of Invention

Stefouch: It's a pretty sweet card; nice to get another artifact tutor. However, with the direction I may be taking this deck, I feel it's going to be too slow, at least in my build. I'm sure in others it will work fantastically.

I love the changes. How are they working out?

You should try Tainted Pact over Lim-Dul's Vault (or over another slot). If you get one combo piece in hand, Pact serves you the other on a silver platter- at instant speed, no less, and with no life loss. Directly into hand, too. It's one I'm trying out now and I'm loving it greatly- doesn't work well for grabbing Ad Nauseam or Doomsday, but absolutely phenomenal for putting a LED/Salvagers, Gorger, a reanimation spell into your hand, getting Faithless Looting, etc..

Lilbrudder: They aren't doing too bad. I'm still getting used to playing Doomsday (and Intuition for that matter), but I think with more practice, I should get it down fairly well.

PookandPie: Tainted Pact might not be a bad option to run, as you said, it adds it to your hand so you can potentially combo off right after.

Made some more changes to the deck:

OUT:

• Angel of Glory's Rise
• Anguished Unmaking
• Counterspell
• Grim Monolith
• Impulse
• Negate
• Recruiter of the Guard
• Vandalblast
• Winds of Change

IN:

• Frantic Search
• Izzet Charm
• Laboratory Maniac
• Mental Misstep
• Mox Opal
• Necromancy
• Pull from Eternity
• Silence
• Thirst for Knowledge

Last night I played a game on MTGO vs Jeleva, Rashmi, and 5c no rare deck. Jeleva was in the process of comboing out. He played Time Spiral and I was able to draw Dark Ritual and Necromancy off of it. He cast Windfall, retained priority, and flashed in Notion Thief. Thankfully, I had Breya out with enough mana out to kill Thief and Necromancy it back. He scooped after that.

That's pretty hilarious.

The best instant-speed one I had was animating Worldgorger Dragon using Necromancy during my own upkeep in response to a Tangle Wire trigger. I had a Prophetic Prism in play so I drew 80 cards and produced 240 mana during upkeep, played a bunch of instants, including Izzet Charm to discard a Snapcaster Mage and moved the Necromancy over to snappy. Went to my main phase with an overflowing grip; cast Animate Dead on the WGD and was done.

Loving the changes! I've always wanted to see her as a Doomsday commander.

Although, you might want to check your primer!

kaboomeow: Thanks! I'm liking them as well. I would like you to know that mmcgeach is the innovator of the Doomsday Breya list; my list is based off of his.

As far as the Primer goes, I am currently working on it and will hopefully have it updated by next weekend, if not sooner.
