Landfall — You may put a +1/+1 counter on
target creature you control.
Whenever a creature you control with a +1/+1
counter on it dies, you may pay {g}{g}. If you do,
return it to the battlefield under your control.
At the beginning of your upkeep, you may
sacrifice a land. If you do, put a +1/+1 counter
on each creature you control.
