Destruction Gastrolith Combo

This is my take on the Gastrolith Glimpse the Possibilities combo deck that I've had a lot of fun playing around with recently. Not exactly optimized, but I've been seeing an honestly surprising amount of success with it, and the stuff you can pull off with this deck is really funny. The main reason for adding shadow is to play Mask of Torment, which makes the main combo even nastier by doubling the already huge amount of power you get off it.
The gameplan isn't much different for other decks running this combo, it just has a bit more potential. Early on just focus on getting gastrolith and glimpse (and if possible mask, but if not then the combo still works and you can easily get mask out once you've already started comboing off), then just play through your deck and get a million power, recurring glimpse if able with Excavate and Deeptrail Vanguard. Cult Aspirant and Riftfeeder Wasp are there to get real big as you combo. Wincons are Pyrotech Explosion, Subversion of Nature, Rewind, and Doomsday Assembly (that ones my favorite), but they're really interchangable with your choice of big win the game cards, these are just ones that I like. Otherwise, Chronostorm and Draconic Looting do double duty with getting you value and being sigils when you're warping with glimpse.
This deck is really fun, I don't think I've seen anyone run mask with this combo but it makes it so much more explosive. I regularly kill people with a 256 damage Pyrotech Explosion or get a full board of double damage Ticking Grenadin with Doomsday Assembly, it's great to actually be able to play the big mana silly cards consistently.
