Amulet of Vigor---> used to make your bounce lands enter untapped for even quicker ramp!
Summer Bloom---> a key ramp card that allows a turn 2 victory.
Primeval Titan---> the main winner of the deck. This guy is a huge beat stick and a mana ramper all in in 1 card!!
Dragonlord Dromoka---> he gains me life and is therefore good against aggro, and he makes my titan "cannot be countered" because they will not be able to counterspell on your turn.
Emrakul, the Aeons Torn---> He is used for a 1 of huge game winner, play a summoner's pact for him and you'll be done the game as quickly as it was started!
Hive Mind---> usually to be used with a pact for a quick win, but also an interesting secondary card just to copy your opponent's stuff. Very fun to use against storm.
Ancient Stirrings---> used to search for the Amulet of Vigor (or even lands in dire situations)
Serum Visions---> used to really just find anything you're looking for and improve your next draws.
Slaughter Pact---> a quick removal spell that can also be a game winner with Hive Mind on the battlefield.
Summoner's Pact---> used to find the Primeval Titan and also as a winner with Hive Mind.
Pact of Negation---> a zero mana counter spell that protects your combo again also a winner with Hive Mind.
Azusa, Lost but Seeking---> another ramp card to hit that primeval titan faster.
