This is a deck that I actually own and play, and it is a real blast. It is always fun and interesting, not knowing what will happen.
There are a number of things you want to win with this deck. One of them is blast of Genius; play this, target your opponent, and discard temporal trespass to deal 11 damage, and copy it with reverberate or Howl of the hoard, and do it again with either another Trespass, or a Blasphemous Act. You win.
Another way is just burn them out with Prophetic Bolts and Charms, along with maybe one Blast of Genius.
Another Way is to animate a Mishra's Factory, attack, Trigger the raid on Howl of the Hoard, and Play Temporal Trespass and Take three extra Turns. Almost garmented win.
Also note that the Mishra's Factory are great Blockers (3/3, because they can tap to pump themselves). Use The signets to produce the vital coloured mana from these colourless lands. You will need it.
And finally, the funnest way to win. Play Narset if it is safe to do so, and attack with her. GG you win easy. No really, every time I have attacked with her, I have won. You filp the top 4 cards, and can play all the spells. Play all those temprol Trespasses for free, extra turn, and Attack again. Or use Blast of Genius to the dome to finish. The real fun starts when you flip into a Howl of the Hoard or a reverberate. Thigs quickly go insane from there.
Narset is also hard to kill, with first strike and Hexproof, and you have cheap removal and stall, along with counters to slow down the game enough and protect her.
I'll say it again, this deck is really fun to play, I have had 2 life, no cards in hand, and only Narset against my full life opponent with a board of creatures and just attacked, hoping to flip into something. The end result was I took 4 extra turns, drew about 9 extra cards, and did them 34 damage! So much fun!
