I like it!

Sealock Monster is the worst theros uncommon

It's basically a 5/5 defender for 5 mana that doesn't bounce with Whelming Wave

If this deck is not budget deck, i'll suggest Sylvan Caryatid over Golden Hind

You've got Divination, it's got a perfectly acceptable partner in Chasm Skulker

Simple changes:

Add Yavimaya Coast for more color fixing (don't worry about the damage because this if for those moments when you absolutely need one more of THAT color, otherwise tap for colorless)

AEtherspouts to replace AEtherize it will stay around longer and its more painful on the opponent as they have to give up on card draws or give up the cards rather than just back into hand for replay.

Prophet of Kruphix must have in any UG deck. Untap your creatures and untap your lands on your opponent's turn. Guess what, now you have pseudo vigilance and mana open to use those control spells!

Get rid of Cancel and add Dissolve same cost but you also get to scry.

Sylvan Caryatid is a do, not a maybe, it gives mana, blocks Aggro, and can't be targeted.

Hi weisemanjohn,

Thanks for the suggestions.

I was already looking forward to replace Simic Guildgate , AEtherize , Kiora's Follower and Cancel with Yavimaya Coast , AEtherspouts , Sylvan Caryatid and Dissolve . I only need to get them. :P

About Prophet of Kruphix , I'll give it a try. It's really good to play a big creature without worrying about leaving mana for counters/Simic Charm .

feel free to check out my version, Kiora found a hydra, for inspiration, though mine has more of an aggressive approach as opposed to a control approach.

Dissolve is strictly better than Cancel

If your taking Prophet of Kruphix you may want Kruphix, God of Horizons because you can get tons of mana and send some big guys out. Cool deck +1!
