A neat little combo that could win you the game on turn 3 if I'm not mistaken:
Turn 1: Raffine's Tower / Xander's Lounge / Thran Portal (not quite a turn 3 win but still a lot of damage)
Turn 2: Forest + Nishoba Brawler
Turn 3: Plains / Mountain + Twinferno + Gaea's Might
If you have all basic land types by turn 3, Nishoba Brawler should be a 5/3 with trample. With Gaea's Might, its power gets buffed to 10, and Twinferno doubles that with double strike, giving you a total of 20 power for a lethal swing.
If they have any blockers, then it won't be lethal immediately, but Play with Fire and Lightning Strike can help close out the game, as well as a kicked Yavimaya Iconoclast.
Snakeskin Veil and Leyline Binding for protection and removal respectively.
Anointed Peacekeeper for hand-disruption and baiting out removal.
Phoenix Chick for an early evasive threat that you can pump with Gaea's Might for good damage in the air.
Rabbit Battery to give non-hasty creatures haste. It can also survive creature sweepers if equipped.
I'm still unsure about what the best distribution of lands in the deck is to ensure quickly enabling domain, feel free to make suggestions. The same goes for most of the support cards. Realistically, the best way to play a deck like this is to include a few less janky combo pieces like Twinferno and use those slots for card draw and/or protection (Fable of the Mirror-Breaker
comes to mind) to increase consistency, but the thought of getting this to work in an actual game is too sweet not to try at the very least.
DISCLAIMER: I have playtested this deck many, many times on Tappedout. So far, the stars have aligned precisely one time.
UPDATE: Works once maybe every 30 games.
