Terramorph {8}{g}{g}{g} (You may play this as a
tapped face down land with {t}: Add {g}. Turn it face
up for its terramorph cost. Terramorph only as sorcery. Playing this as a land counts as your land drop for the
turn.)
Trample, reach, vigilance
When Elder Oak Bear attacks, other Plants and
Trees you control get +2/+2 and trample until
end of turn.
