Example deck I came up with in a few minutes:
5i4 5i4 5i4 5i4 5i4 5i4 5i4 5i4 5i4 5i4 5i4 5i4 5i7 5i7 5i8 5i8 5ih 5ih 5l9 5l9 5l9 5l9 5l9 5l9 5um 5um 5um 5um 5um 5um
Replace all Photons with Enchantresses. Devourers and Enchantresses come out ASAP, Flooding allows you to guarantee control over all but one creature unless dealing with Quint, and Ice Bolt finisher. Freeze is to give you another option if you're low on health or an enemy creature has a nasty ability.
Disadvantage: unless your opponent plays some heavy hitters or you have Sirens instead, this deck kills slowly. But then Water has always been more about control than about rushing.
Thoughts? I'd really love to hear from the Curator on this card, so it can qualify for the Crucible.
Another interesting tactical function of this creature's ability: if you have a frozen or delayed creature on your team, you can use this to speed up recovery.
