This is a rush. It fails vs any type of mass CC or shield. (Single target CC hinders it, but probably won't stop it.)

It gets turn 4 wins, and very rarely takes over 6 (on a not-awful draw)
Scenario for a perfect 4 turn win:
Turn 1: 4-5 aether towers, 2-3 flies. Play all.
4-6 damage.
Turn 2: Fractal. Use it.
24-28 damage.
Turn 3: Blitz. Use it.
64-72 damage.
Turn 4: Blitz. Use it.
104-116 damage.
OR
Turn 4: Fractal. Use it.
100-110 damage.
Scenario for a mediocre 6 turn win:
Turn 1: 5 aether towers, 1 fly, 1 blitz
2 damage
Turn 2: fractal
18 damage
Turn 3: fly. Play blitz.
54 damage
Turn 4: aether tower
72 damage
Turn 5: fly
92 damage
Turn 6: blitz.
132 damage
The only real requirment for an extremely fast kill is 4+ aether towers by turn 1, 1 fly and 1 fractal by turn 2.
It does suffer from severely nerfing itself by drawing a hand like 4 fractals 3 blitz, but this is rare. You *can* still win AI3 from this point, but it might be worth just rage quitting and starting another fight to save time.
It miiight be a good idea to get rid of some fractal/blitz's. But i havn't done the maths on draw probabilities. If someone wants to do them, i'd really appreciate it.
