Two Streams Facility
Whenever you planeswalk to Two Streams Facility and at the beginning of the first upkeep of the game, each player chooses green anchor or red waterfall.
Each player who last chose green anchor may play an additional land during each of their turns. Creatures controlled by players who last chose red waterfall get +2/+0 and have haste.
Whenever chaos ensues, each player who last chose green anchor chooses red waterfall, and vice versa.
