Abuse Itlimoc by untapping it multiple times in a turn to win with gigantic X-cost spells/pumping Ballistas an enormous number of times.

Do not keep 1-land hands if the land can't make green mana, and even then it's questionable, but because this deck only plays 21 lands, you have to accept some one-landers--just remember that all you need to get started is a green source and one other land--preferably an Aether Hub to make Vitalists amazing.

Currently considering: 4 Supreme Will vs 5-mana Nissa and Pull from Tomorrow, 4 Attune with Aether vs Servant of the Conduit and Vizier of the Menagerie #3, and should I pony up for Vraska's Contempts to use instead of Battles?
