you should run Capsize , Mystic Speculation , and a Sapphire Medallion , check out my build if u wanna look for more spells with buyback spells : Talrand, Buying it All Back

Terrain Generator could be handy

The Cipher mechanic works wonders with Talrandhttp://gatherer.wizards.com/Pages/Search/Default.aspx?text=+[cipher]

I thought about Hidden Strings and Hands of Binding but i never thought they'd do much by themselves. The other blue cipher spell sucks. I'll try them though. Thanks for the suggestion.

You could play Tidings . It is great draw.

...Jace's Ingenuity ?

Considering you "draw the shit out of your deck", it would be interesting to have a Laboratory Maniac there. Just "draw the shit out" as you said yourself, then Laboratory Maniac -> Draw a Card (any instant, sorcery or even activated abilities for that...)

Also, Stormtide Leviathan would do wonders in this deck.

I'd also consider an Archaeomancer . Just get something to be able to bounce him (maybe Deadeye Navigator or some other card that would make you able to bounce him every turn) and you'd be able to play your instants/sorceries an infinite amount of times (or until it is killed, although with a Deadeye Navigator he probably would never die, as you would be able to exile him just before it gets exiled/killed, activating the ability as an instant)

I intend to get Laboratory Maniac as soon as possible. The deck just needs it, even if just for Enter the Infinite . I found that tapping out to play a huge creature was usually a bad idea, so I cut the big ones. Having only one in the deck and talrand having hexproof paints a big target onto its back. Inkwell Leviathan could be nice though. Comboing Archeomancer with Repulse , Into the Roil and Voyage's End is just too cute not to try it. Thanks!
