Aqueous Form

Care to clarify what's so great about that card, please? Because I prefer creatures that are unblockable over auras that make them unblockable. And I don't think that 1 card with scry 1 (per turn) will have much inpact on the deck...

What about Bident of Thassa ?

The Bident is a very good addition since it works as a 2nd Coastal Piracy . And I've considered it. But I don't know what to remove since everything seems to have a place in this deck.

I wouldn't mind a Mindleech Mass in this deck. :)

I love Mindleech and it was in the deck in a previous version. Yet it had some big mana problems and I had to cut some of my high cmc cards. This was one of them. I decided to keep Silent-Blade Oni and Wrexial, the Risen Deep instead. Wouldn't mind adding it though.

I might have to reconsider the deck with either discard+reanimation or a way of cheating stuff into play (Quicksilver Amulet comes to mind)...

C14 is close at hand! Assault Suit, Crown of Doom and Dulcet Sirens might be interesting here, forcing more damage on an opponent each turn and helping my Sygg's plans of world domination!
