The resurrection kind of worries me.
It seems like having lots of survivable, front-line resurrection power means that its pushes will snowball very hard:
Its shield covers it for a push against an enemy position, and the accompanying units clear the defenses and the enemy artillery.
The funnelweb quickly pops the artillery back into being, while it keeps marching forward.
At the next enemy position, you now have twice the units.
I'd say that it should, instead of resurrecting, be given the ability to build basic defenses(cheaper than Desolator) and have its buildpower reduced to 50. This would enable it to assist heavy pushes and hold the land behind it, similar to an upgraded commander, but not gain massive momentum as it pushes. Essentially, it would be for taking and holding an enemy position, not for rolling across the entire enemy base.
