Gift a tapped Serpent (You may promise an opponent a gift as you cast this spell. If you do, they
create a tapped 2/2 green Serpent creature token with Reach.)

Gain control of target opponent's basic forest
until end of turn, and untap 5 target lands you control. If the gift was promised, instead gain control of target forest, tapped lands you control remain tapped.
