love the title, +1.

I'm too lazy to look up Heirloom, but according to your description, it looks like all of your mythics and rares are too expensive for the format...? Not trying to be a smartass here, but am I missing something?

Thanks, Gattison.

Are you looking at the MTGO prices?

Oh, no I wasn't. That's what I missed. My bad, and thanks for answering. =)

No problem.

An option more of a side grade to your Sweltering Suns is Anger of the Gods so you can just exile the annoying creature instead and avoiding the death triggers of them as well. you also might like using Dragon Tempest so you can get your dragons haste and begin pinging your opponent when you drop dragons like your Scourge of Valkas does. Stormbreath Dragon is also a good sideboard card against big white decks since it won't get hurt. my last suggestion would be Purphoros, Bronze-Blooded for the same haste to your board but also a way to cheat out a extra dragon to swing with in a turn.

So i just noticed the no sideboard message but apart from that suggestion the rest holds up i think. have a good day and enjoy running people down with dragons!

Thanks, Hachendis.

I chose Sweltering Suns over Anger of the Gods because the risk of having a useless sweeper stuck in hand is greater than the risk of facing creatures that are better to exile. Also Dragon Egg is better with Suns, for whatever that's worth.

I don't really like Dragon Tempest because it makes good situations where I'm able to cast a bunch of Dragons better at the cost of making bad situations where I'm stuck on mana or not drawing Dragons even worse. I don't think the chance that it's both good and not win-more is more than the chance it's a dead card when I'm losing.
