Yes, the reason I said Golem is because they are 'little SC's vs Squiddies and when taking on any underwater any nation you will have alot of provinces that can attack your coastal lands and you can attack as well.

Also Golem is a Commander, so it does not need a commander to drive him around; which is one issue that you will find with armies of Crushers and Clockworks; if their mage commander(s) die (because he's the only thing with a mind, so all the Squids target them) they all die too
