[Standard] Merfolk Mill - Any suggestions to improve?

Merfolk Mill

Use unblockable creatures to draw and mill, and by drawing you mill your opponent. Use Siren Stormtamer, Essence Scatter, Deep Freeze, and (maybe) Merfolk Trickster to keep threats off the board and delay your opponents so long that they get milled out before they can touch you. Use merfolk tribal with Seafloor Oracle along with Curious Obsession on unblockable creatures to draw massive amounts and cards and keep on milling, as well as milling due to you attacking because of Navigator's Ruin.

Any suggestions for the deck?

A Fleet Swallower or two couldn't hurt....

I like this deck. Will try it in Arena if I get the change.

Revision 3

After some playtesting, I can confirm the deck was basically unplayable due to my number one fear before even playing it at all: a severe lack of creatures and extreme weakness to creature removal. I feel that Deeproot Waters in the main and Kopala, Warden of Waves in the SB address this problem, although I think Kopala is better in the sideboard because he wouldn't really be necessary all the time. Also, Admiral's Order is definitely better than Essence Scatter as it can possibly only cost a blue to cast because of the swingy strategy and can counter stuff other than creatures, so it is more flexible, but Syncopate is in the SB if you need to keep your opponent more under control even further. I also removed Deep Freeze because I feel it didn't really work that well in the deck/wasn't super necessary and I would rather make my deck faster with more merfolk using Deeproot Waters than make my opponent kinda slower with Deep Freeze, although it might still have its uses. Does anyone have any more comments or suggestions based on the changes? Make sure to tell me so I can keep improving the deck as I continue to playtest and theorize!

Added/removed cards:
-3 Deep Freeze
-4 Essence Scatter
+4 Admiral's Order
+4 Deeproot Waters

i don't like 3 deeprot water, is very very slow card

[Firestorm258]

I have thought that could turn out to be the case but I have yet to play-test the deck with that card in it, so I'm going to try it out first before I write it off as being too slow, as it has the chance to create really great value and solve quite a few of the decks problems.
