DISCLAIMER: This deck is jank. It's amazing, complicated and fun, but jank.
2.0 version of my previous deck. Still relies on Possibility Storm, but can also win via Hive Mind. Added green for ramp.
Basically, my win cons with Possibility Storm are unreliable. However, it makes my opponent's strategy even more unreliable than mine. Ramp into a Possibility Storm and if it doesn't get countered you can definitely mess with the game plan of a few decks. (Especially control.) The fact that there is surprisingly little enchantment removal in modern (or at least in my meta) makes things a little easier.
Deck strategy:
The thing about Possibility Storm is that once it's down, everything becomes unreliable, counterspells and removal especially. This deck attempts to use this to its advantage. The card type I am mostly targeting with Possibility Storm is enchantments.
Mana Bloom is a 1-mana enchantment that, if cast off of Possibility Storm, will enter with no charge counters and be returned to my hand at my next upkeep. This means that if I cast any enchantment with Possibility Storm on the battlefield, I will either hit Mana Bloom (which will just go back to my hand and be turned into another enchantment), Possibility Storm (the more the merrier), Hive Mind (wins with Pact of the Titan or Intervention Pact, even with a Possibility Storm on the battlefield), or Omniscience, which pretty much wins me the game.
Alternatively, any mana dork, in addition to helping me get Possibility Storm out faster, can be turned into any one of the Eldrazi Titans I have in the deck.
Also,
Rampant Growth
turns into Enter the Infinite. Put Omniscience on top of your library, cast it with Possibility Storm, and cast everything from your hand. Also, any card you cast afterward will end up on the bottom because of Possibility Storm, so don't worry about decking yourself. Also, you have every single Hive Mind and every single pact in your hand, so you should be able to win the game before you have to draw again. Alternatively, just keep one of your Eldrazi titans in your hand (Probably Kozilek because drawing cards is pointless now) and discard it with the majority of your hand due to max hand size (at the end of your next turn) and it will shuffle your graveyard (which now includes most of your deck) into your library.
Ideal draw:
Turn 1: Birds of Paradise
Turn 2: Morph Rattleclaw Mystic
Turn 3: Unmorph, cast Hive Mind, and once it resolves immediately cast Pact of the Titan/Intervention Pact. Profit. (Note that your opponent cannot respond with enchantment removal targeting Hive Mind before you cast your pact because you have priority. Counterspells still work against you, of course.)
Not super competitive but very, very fun. (Also confusing to play with and against.) I went 2/2 with it at a Modern tournament.
WARNING: This deck scoops to Gaddock Teeg. There are Lightning Bolts in the sideboard specifically for him.
