For the lolz, but not quite the fastest, can win on turn 5
Designed for The Rogue Master Brewer competition (http://roguedeckbuilder.com/rogue-master-brewer-2-rally-ancestors/)
Our goal is to mill cards into the graveyard (DRAGONS) we then play Dragon Tempest then
Rally the Ancestors
for 5 mana (x = 3) to return 4 or 5 dragons. the damage done is the number of dragons squared (so 4 dragons does 16 damage, which is generally enough).
We then side out the creatures and make lots of mana to do an uncounterable banfire or Polymorph into Emrakul, the Aeons Torn
How does the deck work?
It has a very similar way to win as scapeshift, when we cast
Rally the Ancestors
and return our dragons, they all enter at the same time, triggering Dragon Tempest multiple times. We want as many ways to dig as possible, that ALSO but cards into the graveyard.
What's the sideboard plan?
We are going to next level them!
Side out
-4x Slumbering Dragon
-4x Dragon Hatchling
-4x
Dragon Egg
-3x
Rally the Ancestors
Any graveyard hate is now useless YAY!!
Side in
+3x Banefire Make infinite mana with Fatestitcher, Intruder Alarm and Forbidden Orchard for an uncounterable Fireball
+4x Raise the Alarm
+4x Polymorph
+4x Emrakul, the Aeons Torn
Oh, but wait, Emrakul, the Aeons Torn gets haste from Dragon Tempest, swing with a 15 / 15 annihilator 6 on turn 4?!?! YES PLEASE
Next level them again by switching back to the original combo!
