Destroyer has some potential but I'm somewhat skeptical.
As people mention in that thread, you need both heal support and rally support to make it work. There are already other cards that can carry matches for you with heal support such as Elemental or Gorivore, and they don't need rally. Especially in the current meta (SC and other popular siege), rallying high wait cards can be problematic, because taking time to set up gives your opponent time to take out your structures. Most of the good current decks that use structures also use quick offense to protect them. Bulldozer is a good alternate source but is just one card and can't really be relied on.
Still, I would be curious to see something like...
Draco
CC X3
Waypoint
OPollo
Bulldozer
2X Destroyer
Plasma Field
Support Carrier (2 if no pollo)
I think you need the 4 structures to ensure CC activation, but having them creates other problems. I would like to see more SCs but not sure what to replace. Still doesn't look quite right but I think there might be a good deck out there somewhere.
The other 2 cards are decent but not really worth much discussion.
