Some thoughts:
- If the deployment zones are 24" deep, is it even necessary to have such a big board? Not much is going to happen in the back half of either deployment zone, so you might as well just make it a 4'x4' board with normal 12" deployment zones.
- The Corrupted Planets rule confuses me. As Pluisjen pointed out there's no reason to ever use it, and it also feels a bit random thematically.
- Teleport Shaft doesn't specify who decides where the unit is placed — depending on that, this could be either a positive or a negative effect.
- Overall there doesn't seem to be much reason to stick around in the deployment zones long enough for the Wormhole Effects rule to become relevant.
