2018 GP Vegas Modern Tooth an Nail (Modern)

My take on the Tooth and Nail Archetype which I'll be taking to the 2018 GP Las Vagas (and hopefully will do well with). Basic plan is to ramp extremely hard and cast a Tooth and Nail as early as turn 3. With Tooth and Nail, you find and Play Emrakul, the Aeons Torn and Xenagos, God of Revels. Xenagos triggers which gives Emrakul haste and +15/+15 and you swing for Lethal. My personal contribution to the deck is to add the madcap combo as an alternate win condition. Since the decks main goal is to cast a 9 drop, having 3 Emperions isn't a detriment since they can be cast as early as turn 3 and reliably by T4. We effectively have 7 copies, 4 of which only cost 4 mana. This tightens up our worst matchups (affinity, burn, and other hyper aggressive decks) and gives us time to find a Tooth and Nail (or alternatively, draw Kessig Wolf Run or Xenagos and beat down).
Typical Gameplan:
T1: Land; Mana Dork
T2: Land; enchantment based Ramp
T3: Land; Garruk / Madcap / more ramp
T4: Tooth and Nail / -4 Garruk / Hardcast Emperion / Primeval Titan to find Nykthos + Kessig
