Enter the Infinite!

The combo is:

ramp into Possibility Storm as early as turn 3. Start casting random sorceries in the hope you will hit Enter the Infinite and cast it for free. (you can also use Unexpected Results to try and cast ETI for free) then draw your library. leave Borborygmos Enraged on top of your library. play an Elvish Mystic (remember you have your entire library in your hand) and Possibility Storm kicks in, letting you cast the Borborygmos from the top of your library for free. then discard all your 24 lands (again, your holding your entire library) and each on does 3 damage.

Another win condition is in Mercurial Chemister . if you accidentally draw an Enter the Infinite during your draw step, pay 2 mana, tap Mercurial Chemister and discard ETI, dealing 12 damage to the opponent.

the dissolves and fogs are there to stall the game until you can find the possibility storm or another combo piece.
