Arixmethes Combo/Voltron (EDH / Commander)

This build has two euqally strong ways to win the game:

1.Coammander.
Arixmethes raw power is very high and combined with unblockable effects he's dangerous but if you get a double strike effect on him he becomes deadly.

2.Go Infinte. 2-4 card combo
The strategy is to use Freed from the Real or Pemmin's Aura to produce infinte green mana with Arixmethes but you can also use the few creatures that untap a permament or land to produce infinte green mana with Arixmethes, as a land, or a diffrent mana source that produces 2 mana with aleast one being blue.
Then you only need a draw spell like Blue Sun's Zenit to FIRST draw your entire libary and then to cast every green and colorless card in your hand to be able to redraw that Blue Sun's Zenit and then to kill off your opponents one by one by letting them draw thousands of cards.
Rinse and repeat.
Sometimes you can't find a draw spell but you can still use all that mana to cast a huge Altered Ego or Nimbus Swimmer to kill your opponents.

There's some room to improve this deck. One could add some better lands or diffrent draw spells or wincons in general.
