Mother Earth

Add a +1/+1 counter on Mother Earth for each
forest you control. When Mother Earth dies, you
may add these counters onto other creatures you control.
{2}{r}{g}: Sacrifice Mother Earth, all forests you
control are given 2 +1/+1 counters and are 0/0 elemental creatures. They're still lands.
{4}{b}{r}{g}: Exile Mother Earth, do the same as sacrificing her but instead all lands are given this.
