Land Equilibrium

[heiner]

1.
Player A has a Land Equilibrium and zero land in play.
Player B has one land in play. Player B puts a second land into play. Does player B need to sacrifice one or both lands?

2.
Player A has two Land Equilibrium and two lands in play.
Player B has two land in play. Player B puts a third land into play. Does player B need to sacrifice one or two (because two equlibriums trigger) lands? Or does the second trigger re-check the condition on resolution?

3.
Player A has two Land Equilibrium and two lands in play.
Player B has three land in play. Player B puts a fourth land into play. Does player B need to sacrifice one or two lands?

1. One land

2. Two lands (Edit: Misread this one. Thought both players would be going to 3 lands in which case the second replacement effect would not apply as the opponent has less lands than the LEx2 player. Bactgudz is indeed correct.)

3. Two lands

Not a trigger, but a replacement effect.

[vaughnbros]

The opponent sacrifices one land per each copy of land equilibrium in play assuming the opponent meets the condition of having at least as many lands as the controller of land equilibrium.

[bactgudz]

1) one land
2) two lands
3) two lands

In both 2 and 3, the replacement effect from the second replaces the land being put into play from the first. So the effect essentially has become:
"puts that land onto the battlefield then sacrifices a land then sacrifices a land."
