Elves of the Realms (EDH / Commander)

Primary mechanics are Elves, Life Gain, Additional Lands, Creatures tapping for Mana, and Elf Synergies.
Prepare for a deck of high life gain, low mana cost, and almost entirely elven armies, with several ways of buffing elves, green creatures, and white creatures, as well as a Commander designed to facilitate quick and easy drawing of cards. As per the usual it has a great deal of 'I help you, you help me' cards to offer means of rewarding opponents for keeping you around, although they will be hard pressed to kill you in any event.

Infinite Hand, and Life:
Armorcraft Judge + Wirewood Symbiote + Venser's Journal + Counter Generators & Token Generators
