A standard deck that revolves more around surviving and taking over the late game rather than trying to win as fast as possible.
Hopefully a lot of the deck is straightforward enough. There are very, very few creatures below CMC 3 (Caryatid is the only one) and past that all creatures have a toughness of at least 4 (to avoid lightning strike).
The deck can potentially have a weakness to decks that can grind out even longer (control maybe be able to possibly just draw-go for a few rounds) however it should be pretty decent against any deck that relies mainly on creatures.
Although it may look fragile, there is a decent amount of life gain in the deck and the big toughness on creatures can diminish the damage from most cheap, aggro creatures.
Sideboard:Thoughtseize: Not in mainboard because, 1) the likelihood you can pull a turn one Thoughtseize with this mana base is unlikely, and 2) it's almost unnecessary. Good against control, but what can another deck do to us that will really want us to take more damage?
Suspension Field: Decent way to get rid of those actual threats.
Reclamation Sage: I am not worried enough about Gods to run Unravel the Aether (after all, we still have Utter End and Banishing Light). Here, I get a body and I can get rid of opponents Courser's or maybe their own Suspension Fields and whatnot.
Rakshasa Deathdealer: An odd one, this card comes in against other midrange and control decks. You can't exactly block it with a Caryatid (unless you don't mind losing your mana-man) and it just has overall fantastic qualities. It can always get bigger, and it can always regenerate.
Garruk, Apex Predator: The one of, I still don't believe this Garruk to be of that much use, but in a grindy matchup, he can find his place.
Banishing Light: An overall good card, can get rid of just about anything.
