Chop Down

Choose target creature you control and target
creature you don't control. If the creature you
control is an Ent, it gets +1/+0 and gains
indestructible until end of turn. Then those
creatures fight each other. (Each deals damage
equal to its power to the other.)
"Give me six hours to chop down a tree and I will
spend the first four sharpening the axe." - Abe Lincoln
