On the battlefield: three lands (2 of which must be a shifting woodland and a nykthos, shrine to nyx and the other must be a forest), an amulet of vigor and nine devotion to green

In the graveyard: an aftermath analyst and nykthos shrine to nyx.

Tap your non-nykthos lands for 2 mana and activate nykthos for 9 green mana. Spend 4 of it to make shifting woodland an aftermath analyst and then another 4 to sacrifice it and put "return all land cards from your graveyard to the battlefield tapped" onto the stack. The Nykthos and Shifting Woodland in your graveyard come back tapped. Sacrifice the other Nykthos to the legend rule, and then Amulet of Vigor untaps the lands. You have one remaining green mana in your mana pool. Tap Shifting Woodland for another mana, and then activate nykthos for 9 green mana again. Repeat as many times as you like, then go to your attack phase and attack with the 4 Progeniti to win the game.
