Atraxa, Grand Unifier (EDH / Commander)

PORPOUSE OF THE DECK:
The idea of the deck is draw a lot of cards, and win with commander damage while you win lifes and protect yourself.

This is not a cEDH deck it is Casual deck without infinite combos and None Massive Lands. You can fun fighting against casual and preconstructed decks.

1º MANA BASE:
Although the commander has 4 different colors, the deck is mainly based in 3 of them: green, white and blue. It hasn't too much black colour spells.

I am sure that you are thinking about fetch lands, double lands al all expensive resources. However, I am thinking about a balance between deck price and strong.

There is to use lands in order to get things. With Tatyova, Benthic Druid, you can draw a card for each land enters in the battlefield.
Mystic Sanctuary can be used to recover spells and use Trade Routes to return Mystic Sanctuary to your hand and play it again in addition to discard lands and play them from graveyard with Conduit of Worlds.

It would be marvellous if you could have Exploaration in your battlefield linked to previous habilities mentioned in the last paragraph and Wayward Swordtooth would give an aditional land to you too.

There are a lot of mana sources divided in different actions:

• IMPORTANT LANDS:

• Lands that you are going to use for draw card:
  The Surgical Bay
  The Hunter Maze
  The Fair Basilica
  The Dross Pits
