Although those are interesting considerations, I'm not interested in removing Future Sight. Even if my opponent's see my deck's top card, I don't mind it. It allows me to play lands from there, hard cast stuff from there if I want. Its pure card advantage. I like it a lot. Far more than Sphinx of Jwar Isle although that's a cool card. Something I had considered in a previous version.

Crab Umbra is quite cool. I still prefer Pemmin's Aura in general but I will have to pay close attention on how my games go to see which one is most effective and swap it out if needed be. Thanks for the suggestion. Added to my maybe board.

The mana dorks aren't perfect but they can be sacced both to Jalira and to Arcum Dagsson (this guy IS good enough to get its own deck; not doing it though since I find it a bit too broken/unfun a general though). I would prefer more stuff like Chronatog Totem but there aren't that many rocks that turn into creatures... From the games I played I'd say that I either cut on these and add small stuff that can be sacced or produce more tokens. Since these guys serve 3 purposes (again, mana dorks + Jalira + Arcum) I still prefer them over other things.

I do agree though. What needs to be cut down are the creatures. Everything else seems sort of fundamental for the deck to run smoothly.

Cauldron of Souls for double the jalira triggers per creature, and board wipe protection.

Not a bad option either. But that means I'd have to free another spot for it. Furthermore, would have to change a bit another deck (which might not be that much of an assle). Taking it into consideration. :)
