Bountiful Pastures

Bountiful Pastures enters the battlefield tapped.
At the beginning of your upkeep, put a season
counter on Bountiful Pastures. Then, if there are
four or more season counters on it, remove all
season counters from Bountiful Pastures and
create that many food tokens.
As long as Bountiful Pastures has no season
counters on it, it loses all other activated abilities
and gains: "{t}: Add {s}."
