It's a logic variation. There's a very similar suggestion with a few more attackers, permafrost, ice lances rather than squids, but without the healing.
In other words, it is one concession or the other. Personally, I think 6 attackers is low. AI5 is not completely without CC. I think one AI has a diamond shield too.
You may be onto something, if the squids become cannon fodder rather than CC.
I consider permafrost a must, which is not nice for the deck size.
I'll give it a try, but I don't expect many differences with other mono water decks.
Oh, I would go with something like ''deep purple'' or ''frozen purple.''
