Elder Wyrm, Revenant Soul

Reach, Deathtouch

When Elder Wyrm enters the battlefield, each opponent sacrifices a nontoken creature or a nonbasic land.

At the beginning of each opponent’s upkeep, if they control more creatures or lands than you, they lose 2 life and you create a tapped 1/1 green Saproling creature token.

Whenever a creature you control dies, you may return target land card from your graveyard to the battlefield tapped.
