This deck is really complicated to play with, but play it right, and you can actually go from 5 to 183 health, then do 150 damage and completely annihilate your opponent in one turn. With 7 lands.
How does this happen? The answer is Aetherflux Reservoir.
Now, to do this incredible feat of 13 spells in one turn is pretty hard, unless you have cards like Inspiring Statuary that allow you to cast those more expensive spells like Baral's Expertise.
Paradoxical Outcome, Baral's Expertise, and Reverse Engineer are the main ways to get more cards out and more spells cast.
Do not start casting spells until Aetherflux Reservoir enters the battlefield unless it is Inspiring Statuary, a tutor card, or cards that generate lands for you if you need them.
This deck is prepared for when Ixalan comes out so it will be still standard legal. The cards on the maybeboard are really good cards for this deck that will be going out of standard soon. As Foretold is just there to cut down the expenses in case you just have a 20$ budget.
Admittedly, I got this idea from https://www.mtggoldfish.com/deck/680714#paper but that one doesn't accommodate for Ixalan, so I wanted to make one that was. No suggestions or comments on this deck are bad, so don't be afraid to provide them.
