That's a very good idea. I hadn't thought of that. Thanks for the idea. Sorry it took me awhile to get back to you.

A suggestion for what you could exchange the Lavamancer for is Runaway Steam-Kin. It can provide mana if you need it, and is a big beater if you don't.

Welcome, and as I was looking at my comment, I realized it souded a bit sarcastic, I didn't mean it that way

Also, just to let you know, in commander your deck has to have 100 cards exactly, including your commander, so usually a 99 card deck. No more, no less.

You're Welcome.

Maybe add Blackblade Reforged, because if you control 8 lands, and in commander thats not too hard, Blackblade plus Kalemne is an insta kill.

I'd say that Thundermaw Hellkite is a sideboard card, but it does work in the deck, so it's up to you.

Two things, one Marwyn, the Nurturer might do well in this deck, and, two, you might want to add one more card to make this deck legal. :)

I would recommend changing this deck to standard, because the only cards that make it modern are Birds of Paradise and Ancient Ziggurat, and, while both of those cards are good, this deck would preform better in standard. Also I would recommend adding some removal in your sideboard.

Very ingenious use of Arcane Adaptation, yet another use of the card that, when I first pulled it at the pre-release, I thought of as a junk rare.

Happy to help, forgot about Harnessed Lightning, and speaking of Harnessed Lightning, you probably should remove one Lightning Strike from your sideboard, and add in a Harnessed Lightning, because, in your deck, Harnessed Lightning is better than Lightning Strike.

My commplements to you sir, the deck is very cheap, and it also looks like it is a fun deck, however, in my opinion, your deck looks a bit land light, and it has no targeted removal. So I would recommend to add cards like Prey Upon, Hunt the Weak, Bombard, or lightning strike.

By the way, I forgot to ask, how has the deck been working?

And for sideboard, the best way to determine your sideboard, in my opinion is just to keep on playing, if you're noticing that you're continually losing to one architype, then add a card in your sideboard to counter it. But just by looking, in my opinion, it looks like your deck can handle most deathtouchers with abrade, and it can deal with most other creatures, however it doesn't have a lot of flying removal or token control, so if you're facing a deck that has one or two huge flyers, or a deck that has a ton of tokens with hexproof, *cough* merfolk *cough*, then you'll kinda be at an impass, with the unblockable thing that merfolk has. So I would recommend a card like sweltering suns for merfolk/token control. Though this card would destroy your goreclaw, as well as your mana dorks, it might be worth it if it wipes most of your opponents board as well, especially, if you have Ghalta out. For flying control, you have Vivien, but you migh want to add Plumet or Pierce the Skys, though this is a tough call, because Vivien does take control of flyiers pretty nicely. Another thing to consider is more enchantment control, because white has a lot of enchantments at the moment that prevent creatures from attacking or blocking, so something like Naturalize.

Giganotosaurus is an option, quintuple green is risky, but a 10/10 for five, that can gain trample because of rhonas or goreclaw, is nice. But the quintuple green does make it so he can be quite risky and if you draw one of your mountains it will delay him a turn, so its up to you.

Tree of Peridition is a cool card and it also makes a cool combo, when you add Turn to Frog. Setting your opponents lifetotal to 1 is pretty cool :). This combo is a bit weird, it took me awhile to figure out, so I'll explain it.
Step 1: Activate Tree of Perdition's ability
Step 2: While Tree of Perdition's ability is on the stack cast Turn to Frog on Tree of Perdition, and when Tree of Perditions toughness is checked when its ability is resolved, it will be one, assuming your opponent has no instant speed removal.

If you're going to go that route, consider adding a couple aether hubs to your deck for the energy, and they can tap for any color, which is cool.

Looks like an interesting dragon deck, maybe consider adding Lathliss, Dragon Queen, to further benefit off your dragons, or Dragonlord's Servent to make your dragons cheaper, or, if you make this deck a legacy deck instead of a modern one, a Dragonspeaker Shaman to further reduce the cost of your dragons.

Sorry about the multiple posts, cards I forgot about keep poping into my head. Anyway another mana dork is Draconic Disciple.

Also Channeler Initiate, but he and Rishkar are rotating out soon

Another suggestion is Marwyn, the Nurturer, but you would have to add more elves, and you might not want to do that.
