Commander: The Ur-Dragon

Because who doesn't love dragons? Especially The Ur-Dragon? We will start with the stock list given to us a few years ago-because I'm just getting around to this deck now.

Instant	Artifacts 1 Fist of Suns 1 Herald's Horn 1 Mirror of the Forebears 1 Armillary Sphere 1 Commander's Sphere 1 Darksteel Ingot 1 Dreamstone Hedron 1 Lightning Greaves 1 Nihil Spellbomb 1 Sol Ring 1 Wayfarer's Bauble

The first thing I notice is that there are no instants here. Which makes a little sense: this is a brute force deck. Do I have a dragon? Good. Should you have a dragon? No. 

However, there's clearly room for improvement from the stock list. Cards like Taigam and Orator of Ojutai are dragon adjacent at best, the curse cycle here is a deceitful thing, there to convince you that there are early plays when they don't do nearly enough, and Crucible of Fire is one of the most 'win more' cards Magic has ever produced. Dreamstone Hedron is...awful. And Mirror of the Forebears is misplaced in a deck that has a bunch of legendary dragons. 

Part of me wants to replace all of these cards, or nearly all, anyway, with instants. Let's give this deck something to do on opponent's turns! But, looking at EDHrec, I can see that there are better ideas, from thematic fixers like Dragon's Hoard, to ways to keep the gas on like Temur Ascendancy, to clever helpers like Sylvia Brightspear.

But that doesn't mean I should ignore the fact that there are no instants: recommendations like Spit Flame, Terminate, or Sarkhan's Triumph have a place and could go a long way towards making this deck better.

I also want to use a Sensei's Divining Top in this deck, so perhaps just raw draw and land search effects would be fine. Let's take this for a ride.
