Fern, Redeemed

When Fern, Redeemed enters the battlefield,
draw a card for each creature you control, then
gain 2 life for each creature you control.
When Fern, Redeemed dies, exile it and create
Tree House, a legendary land token with
"{t} add {w} or {g}" and "{1}, {t}: Draw a card and
gain 2 life."
"I wish I could see the Tree House one last time, but
that's ok. Just promise to bury me there."
