So this is my first deck that I will have posted on this site. I saw Frontier Siege in the spoilers and figured it could be potentially broken with the right deck. So, here's a crack at a deck with some nasty dragons and a whole lotta mana.
Essentially, the idea of the deck is to ramp up to Frontier Siege as fast as possible, then using it's Khans ability to generate stupid amounts of mana. For example, while Frontier Siege is in play, after combat, Dromoka, the Eternal costs 1 White mana to cast.
Notable Cards:
Dromoka, the Eternal - Makes things bigger with bolster
Stormbreath Dragon - Pretty self explanatory. It's a dragon, it has pro-white, haste, enough said.
Sarkhan, the Dragonspeaker - Becomes an indestructible dragon, therefore triggers the abilities of Dromoka, the Eternal and Atarka, World Render
Atarka, World Render - Giving Double Strike to the dragons is insane.
Suggestions are welcomed and wanted (especially for the manabase)!
