So I will tell you right now, if you just playtest this on its own, you will hate this deck and find this to be the dumbest idea you have seen in a while. If you playtest this against another modern deck, you will laugh hysterically as you realize that this is the dumbest idea I have put together, and an utter pain in the ass to deal with.
The idea of the deck is to stall the entire game, make sure they don't have a threat in their hand, then play [Shared Fate] and beat the living crap out of them with their own deck!
But wait? Aren't they killing you with your own deck?
No! Because your playing Fate Leaked! Which means that your deck is absolute crap! Did they play your Shared Fate? Doesn't matter!! We keep doing what we were doing!
The key to this whole deck is the early game. You have to keep threats off the board and not allow them to get to their win conditions. You have a multitude of ways at looking at their hands, take full advantage before you play [Shared Fate] and once you drop this card, if done right, you win no matter what they decide to do.
Please leave comments and let me know what you think!
PS
The card choices are purposefully meant to not be that useful after early game, so when suggesting cards, please remember that anything that is put into the deck will also be used against you, so you don't want things that could ever give advantage or kill you.
