Win Conditions:

1. With an active Pyromancer Ascension, you can create an infinite mana and infinite mill loop:

    Graveyard contains Manamorphose and Noxious Revival
    Hand contains Manamorphose and Noxious Revival
    Cast Noxious Revival, targeting Manamorphose and Noxious Revival in the graveyard
    Cast Manamorphose to draw the two cards you just put into your graveyard
    Repeat the loop as many times as needed

What this loop does is create 1 extra colour of mana per loop. Repeating this loop creates infinite mana.

    With infinite mana, perform a similar loop by casting Noxious Revival targeting Thought Scour and Noxious Revival in your graveyard
    With Thought Scour added to the loop, you may mill your opponent to death
    There may be different variations to this loop without the use of infinite mana

2. With an active Pyromancer Ascension, Lightning Bolt to the face

This is often your secondary win-con. There are many ways to win with Lightning Bolt, especially when each cast is copied by Ascension. You can rebuy your copies of Lightning Bolt with Noxious Revival and, with my version of this list, rebuy it with Snapcaster Mage. This is a very viable win-con, and happens more than you think.

3. After sideboard, Young Pyromancer and elemental tokens.

This is your usually your tertiary or primary win-con depending on the matchup. With the amount of cantrips and cheap spells in the deck, you can often create an army of elementals to run over your opponent.
