Choose one. If you control a commander as you cast this spell, you may choose both instead.
• Until end of turn, any number of target lands you control become 1/1 Elemental creatures with
vigilance (Attacking doesn't cause this creature to tap.),
indestructible (Effects that say "destroy" don't destroy that permanent. An indestructible creature can't be destroyed by damage.), and
haste (This creature can attack, and as soon as it comes under your control.). They're still lands.
• Choose target creature you don't control. Each creature you control deals damage equal to its power to that creature.
