U/R Aggro

[Kilo]

So having been working on a U/R tempo artifact deck for a little while I decided it was pretty bad. However I think U/R aggro is easily FNM playable at least. To open for discussion here's the list.

[deck]
(Creature)
4x Generator servant
4x Chief Engineer
3x Juggernaut
4x Ornithopter
3x Phyrexian Revoker
3x Scuttling Doom Engine
2x Soul of New Phyrexia
(Land)
3x Island
3x Mountain
4x Shivan Reef
4x Steam Vents
4x Temple of Epiphany
4x Darksteel Citadel
(Instant)
4x Izzet Charm
4x Lightning Strike
3x Shrapnel Blast
(Enchantment)
4x Ensoul Artifact[/deck]

Just for starters I'm still considering cutting Izzet charm for two rapid hybridization and something else. Lightning strike or magma jet is still unclear to me, and I feel like Soul of new Phyrexia is pretty weak and I'd probably just be better off with a fourth Scuttling doom engine and juggernaut. Also I haven't got to do enough
testing to determine an actually useful sideboard so any thoughts on that are very welcome.
