A bunch of land finding and colorless Eldrazi's
The Best Play I could hope for is to go 2nd and the opponent played a creature on his first turn.
My turns would play out like this:
1. Forest, Irresistaible Prey
Mana = 1F Total = 1
2. Mountain, Pyromancer Ascension
Mana = 1F 1M Total = 2
3. Forest, Pyromancer Ascnsion, Irresistaible Prey
Mana = 2F 1M Total = 3
4. Forest, Irresistaible Prey, x3 Explore, Forest, Forest, Forest, x3 Explore, Mountain, Montain, Forest, x3 Explore, Eye of Ugin, Eldrazi Temple, Eldrazi Temple, x3 Explore, Eldrazi Temple, Eldrazi Temple, Mountain, It That Betrays
Mana = 7F 4M 4/8 /2 Total = 11/21 Total Used = 21
5. Forest, All Is Dust, Gain Control of all opponents colored permanents, Emrakul the Aeons Torn, Attack for 11 with "It that Betrays", Gain control of attacked opponents 2 sacrificed permanents(likely land, as most other permanents are colored and under my control).
Mana = 8F 4M 4/8 /2 (2) Total = 14/24 Total Used = 22
5.2. Mountain, Attack for 26 with "Emrakul, the Aeons Torn" and "It that Betrays", Gain control of attacked opponents 8 sacrificed permanents (Opponent is Likely out of permanents to sacrifice by now), Emrakul the Aeons Torn, Put newest Emrakul the Aeons Torn in graveyard, Kozilek Butcher of Truth
Mana = 8F 5M 4/8 /2 (5) Total = 18/28 Total Used = 25
5.3. Forest, Attack for 38 with "Emrakul, the Aeons Torn", "Kozilek, Butcher of Truth", and "It that Betrays", Gain control of attacked opponents 12 sacrificed permanents (Opponent is definitely out of permanents to sacrifice by now and out of Life for that matter)
