Last war, it tested a fractal water deck, but I found you will need a lot of water to fractal crawlers efficiently. Maybe switching to pendulums might help, for example 6 water pillars, 10 pendulums and mark of Aether, that leaves 14 cards. I would say: 4 fractal, 3 mind flayer, 3 crawler, 4 freeze.
Or, make the deck a little bigger, and do 1 more flayer and one more freeze.
