Tree Sentinel

Trample, lifelink
Whenever Tree Sentinel leaves play, create a legendary 5/5 green artifact vehicle with
"Crew 2, trample, and lifelink"(Tap any number
of other untapped creatures you control with total
power 2 or greater: This permanent becomes an
artifact creature until end of turn.)
Life flows in everything, we have the power to
harness that life.
