I don't know if you have thought of this before, but Chromatic Lantern and Mycosynth Lattice combo with Dragon Tyrant really well. by being able to pump him up with any color mana it is sure to land a devastating blow.

Zer0w: Thanks for all the suggestions.

Scroll Rack and Sylvan Library are both cards I want in the deck. However, as you know, space has always been an issue for me. There is no such thing as "filler" in my deck, so it's always hard to make room. Mayael's Aria is decent. However, I cannot stand waiting that long to kill them, not to mention it paints a GIANT target on my back.

And yes, I do know that Chromatic Lantern and Mycosynth Lattice are disgusting when used with Dragon Tyrant. I use it quite often.

MrEM4N: Thanks for the comment! No worries. Everyone misreads cards.

Quarion65: Thanks for the comment!

I cast my dragons sparingly. I try my best to keep them in the deck in order to transform Scion of the Ur-Dragon into them.

However, we don't live in a perfect world, so I do know you'll have to cast them occasionally. Of all the dragons in the deck, the ones you should NEVER cast are Skithiryx, the Blight Dragon, Moltensteel Dragon, and Dragon Tyrant.

Dredge4life Thanks for the comment and the +1!

Yes, emergency Hexproof works wonders.

with the tuck rule changing a while back d you still think Oblation and Chaos Warp are the best removal options?

They also remove non-commander permanents

I second that Mayael's Aria, good idea

So maybe this is more for the budget combo build, but I hit a good combo a couple days ago that I haven't seen. I've been testing Fearsome Awakening--I realized that if you copy Enduring Scalelord with Scion and then bring it back with Fearsome Awakening, the counters trigger each other infinitely so that you end up with two infinite power/toughness fliers--one of which being your commander. It's really not mana intensive for a deck like this, and it is hilarious. Anyone have any thoughts?

That is good... I like Dack's Duplicate a little better.. just turn Scion in to scalelord then cast Dack's Duplicate copy scalelord then attack with at least Dack's Duplicate and it triggers... however if you are the one with the most life then it will not trigger. Dack's Duplicate is a more useful card in other situations. but Fearsome Awakening is useful outside the combo, fits the deck flavor. I haven't seen it before but like it! I think I will add it to my Scion deck.

With the new commanders there is a new land that is worth looking into. Would Command Beacon be worthwhile in this deck? I figured once someone realizes the combo potential they'll try to take it out as much as possible.

I know your deck has been up awhile and someone may have already asked this, but why not Karrthus, Tyrant of Jund? Giving all of your dragons haste with Living Death is an alternate win condition if your opponent realizes they have to keep your commander off of the board no matter what. Two lands I'm curious as to if they are note worthy; Boseiju, Who Shelters All for your sorceries and instants (that could help you last that one turn needed) be uncounterable, and Command Beacon for that one player who realizes that they need to keep your commander off of the battlefield no matter what.

Sidenote: How has Exploration played for you? Is it really needed with all of the signets that you play?

Also just realized I asked the same question twice. It's late where I am. Sorry about that.
