Argeaux,
That's good to know about Architect of the Untamed ... I knew she was underwhelmeing in this deck, but didn't realize it was more universal.

Hipparion,
Just realized I hadn't responded on Renegade Tactics vs. Blossoming Defense. Short story is I value Draw and the ability to mess with my opponent's board state (from Tactics) more than protection from Burn and Control (from Defense). But I may change my opinion once we get a look at the actual meta!

Thanks to you both!

clayperce, is there no Naturalize for 3 mana in standard currently (instant speed)? If so, I hadn't realized.

I didn't see skysoverign (you know, the big vehicle) anywhere in the description, don't know if you have thought of it yet.

As for the deck name, "The Energizer Dragon"? (off of the energizer bunny). Maybe there's already another deck like that...

Hope I could help.

Bovine073 needs to be proclaimed the winner of this comment section for coming up with "The Energizer Dragon." Well done.

Bovine073 there IS a 3 drop "Naturalize" in the Kaladesh set. It's called Appetite for the Unnatural.

I have Appetite for the Unnatural in my sideboard, and ive actually finally playtested Gruul standard attempt. works well if i can get pummeler out!

Have you considered electrostatic pummeler? You already have the energy creators and the means to pump everything and give it trample, seems like it would be a decent fit.

Bovine073, Argeaux, and Athraithe,
Yeah, Appetite for the Unnatural is great, but I'm starting with Root Out, as I generally think the upside (Draw) is better than the downside (Sorcery-speed). I'm not opposed to Appetite though, so we'll see ...
Thanks much!

You may not have seen this in the Strategy and Card Choice section: GREAT CARDS I'M NOT USING AND WHY: Electrostatic Pummeler: Solid option, if this was a more dedicated Energy deck.
Thanks though!

Oh whoops, I sure did miss that, love the deck though. I have a zada/partisan deck and I've been itching to make my playset of mirrorwings work somewhere.

Honestly i didnt even think of root out... May put that in!

reyv6925,
No worries, and thanks much!
And me too, on trying to make Mirrorwing work! Which reminds me: If you haven't already stopped by the Solving Mirrorwing thread, you may wish to do so.

Athraithe,
If you do, please let me know how it goes!

What are some sideboard cards to deal with planeswalkers like liliana and sorin?

PBNSurprise,
For Planeswalkers in general, I'm planning to start the season with just the maindeck Burn (redirected from Player to the Planeswalker), Trample, and Flying. If that's not enough, I like Devour in Flames on the sideboard. Or maybe swap out Mirrorwing for Skysovereign, Consul Flagship.

For Sorin, Grim Nemesis in particular, Goldnight Castigator was a great sideboard against BW Control last season, so her or Skyship Stalker would presumably be great again. I'm also always surprised at how many opponents have no real pokerface ... which can make a Collective Defiance (Mode 1) as they approach very effective.

Just my $0.02 ... I'm interested in others' opinions here too!

Delta-117,
Thanks tons, for playtesting against Dimir Schemes!

I've already got Blossoming Defense on the sideboard, but thanks for reinforcing how much I need it in some match-ups!

I also really like the idea of Key to the City. I love Unblockable effects (I miss Rogue's Passage sooooo much) but I had kind of discounted Key early on, because I didn't think I'd have enough cards for the discard by the time I needed it. The deck does OK though, so I'll give it a hard look!

Thanks again!

My only advise for this deck would be to drop the Longtusk Cub for Bristling Hydra. The hydra's resilience to removal spells makes it a massive target that will pull removal away from your other creatures like mirrorwing.

Other than that, nice brew man +1

albino_ninja,
You may not have seen this in the Strategy and Card Choices section: GREAT CARDS I'M NOT USING AND WHY: Bristling Hydra: Just not as good as the other 4-drop options.

See, Hydra doesn't really compete for slots against Longtusk Cub, but against Fleetwheel Cruiser. Or maybe Lathnu Hellion. Hydra is a big wincon-style beater. Cub is about moving towards the win ... sometimes sneaking in for early damage, sometimes Crewing vehicles, and always messing with my opponent's combat math, since it can grow at Instant speed any time I have spare energy laying around.

Plus, except in matchups where the opponent has ZERO creatures, Mirrorwing Dragon doesn't need anyone else to pull removal away :-)

Thanks though, and thanks also for the kudos!

You need 2 more red sources to cast your stuff consistently. I'd switch 2 forests for 2 cinder glades. You'll still have around a 70% chance of your cinder glade coming into play untapped. I'm assuming there you generally want 2 modes on collective defiance.

Source: http://www.channelfireball.com/articles/magic-math-shadowlands-and-battlelands/

Also you don't need 1 drops to crew copter- it doesn't get haste when crewed, so you actually attack with it for the first time on turn 3. I'd go 2-2 with it and fleetwheel cruiser maybe, or something like lathnu hellion.

11 2-drops is more than enough to crew your copter. If not the cruiser, look again at incendiary flow, as I'm not particularly sold on the burn alternate wincon, when copter is relatively difficult to remove and so a good alternative anyway (and some decent flood insurance, too!)

I'm also not that convinced that the cub is better than sylvan advocate, but I guess having no manlands does reduce its value, and you've played with the deck a bunch. It's certainly not a bad card. I'm also not convinced by brute strength over rush, is the single point of power really that important? I also might go for trying to play blossoming defence main. It's a very, very good card and I hate playing against it.

Playtested at my last standard event. Went 3-1.

Round 1 match up: G-B deliriumResult: very strong win2-0the deck was just too fast for him to do anything. Had enough removal for the 1/1 deathtouchers

Round 2 match up: B-R vampire madnessResult: A win2-1His deck was fast, but this one was faster and had higher quality creatures.

Round 3 match up: bant cluesResult: A very hard loss0-2He made tokens and had so much card draw that the deck never stood a chance.

Round 4 match up: aetherflux cheerios Result: A hard win2-0His deck was just too slow to get his combo off the way he wanted. A very easy match up.

All in all a good deck. Don't know how it would do against grixis emerge or dwarf vehicles though. Only time can tell.

Something to consider when running Mirrowing/Zada effects with pump spells, is to include spells with extra value. I might consider running something like Confront the Unknown or Expedite, over Brute Strength.

Both allow you to filter them away when you just need to draw cards. Both are cheaper to cast than Brute Strength. Trample is nice to have, but you have some creatures with trample already, so that's not always a bonus. Confront the Unknown has even more value when you get it on the dragon; Not only do you get multiple clues, but you can order the stack in a way to get specific creatures a bigger bonus than others (as in +1/+1 to one, +2/+2 to another, +3/+3 to a third, and so on.).

Lol, go look at his deck, Mirrorwing Artifacts (KLD).

UnspokenSaints,
I've found the mana fixing to be just right, actually. More Cinder Glade is a little too slow. And I would rather not change the Red-Green balance anyways ... the deck needs on T2 for Voltaic Brawler, and doesn't really need until T4 for Collective Defiance with Escalate.

Sure, I could Crew a Smuggler's Copter with anything, it doesn't have to be a one-drop. But it seems a waste of mana to do so. 11 Creatures is not enough for 4x Vehicles IMO (let alone Copters + Fleetwheel Cruisers). You might want to check out this article too.

Yeah, I've found Longtusk Cub to be surprisingly good ... the threat of activation really messes with opponents. Sylvan Advocate competes more with Lambholt Pacifist  ^Flip and Servant of the Conduit. I think Servant is just a little better, but they're all really good in the deck.

I like Rush of Adrenaline in a Prowess deck or one that's trying to Storm off a bunch of spells in "One Big Turn". For this deck though, I like Brute Strength better.

Yeah, I'm not really sure yet on Blossoming Defense. There was SO much removal last season, I would have mainboarded it for sure. We'll see how this one goes. But the deck definitely leans more Aggro than Control, so I figure I'll start it in the sideboard.

I appreciate all the thoughts; thanks much!

salistar,
Thanks so much for the match-up report, and I'm super-pleased the deck ran well for you! I've done a lot of testing against Chris VanMeter's W/R Vehicles (#1 at SCG Open) and Zach Voss' Grixis Emerge (and did well) but have yet to meet either on a real table either.

Thanks again!

JimmyDPawn,
You may not have seen this in the Strategy and Card Choices section: CARDS I'M NOT USING AND WHY: Expedite: A Mirrorwing staple, but this deck doesn't seem to need the Haste nor the incidental Draw.

Also, like Nosoup4ne1 points out, I love Confront the Unknown with Mirrorwing. But in another deck, not this one :-)

One thing to note if you're running Confront with Mirrorwing (sorry if you were already aware of this): Because you target Mirrorwing first, the original spell will resolve last. So in your example, the +3/+3 has to go on Mirrorwing.

Thanks!

I really think Blossoming Defense you should have in the mainboard.
