Need side board for G/U artifact

[Dusktreader749]

so far it's:
4 juggernaut
4 scuttling doom engine
3 soul of new phyrexia
3 ornithopter
2 Colossus of Akros
4 dissolve
4 dissipate
4 ensoul artifact
4 renowned weapon smith
2 chief engineer
1 retraction helix
4 elvish mystic

This is all the cards except lands. I need a side board for the deck so anything would help

The Mystics are more important than the engineers only because they allow me a turn 3 doom engine or soul of new phyrexia. I was thinking revoker for side I just need more ideas for side board stuff mostly.

How does an elvish mystic get you a turn 3 doom engine? You are aware that elvish mystics don't get a forest from your deck right? This is a common mistake

T1:
Forest
{Elvish mystic}

T2:
Island
{Renowned weaponsmith}

T3:
Any land
{Scuttling doom engine}

3 lands, mystic produces 1, and weaponsmith produces 2 for artifacts, 6 total.

You can get  {Chord of Calling} In the sideboard for match ups that go long and you need to guarantee a bomb hitting and a few  {Perilous Vault}s in the sideboard to go against heavy creature match ups or walker match ups
