Enchant Plains
{2}: Until end of turn, enchanted Plains becomes a 2/5 white Spirit creature with "Whenever this creaure deals damage, its controller gains that much life." It's still a land.
When enchanted Plains is put into a graveyard, you may return Genju of the Fields from your graveyard to your hand.¹

Gatherer Card Rulings [Nov 2009]

• 8/1/2005: When activated multiple times, it will have the triggered ability multiple times.  When the animated Plains deals damage, the ability will trigger once for each copy of the ability.  If, for example, you activate the ability three times, the Plains will deal two damage, and you'll gain six life.
• 8/1/2008: A noncreature permanent that turns into a creature is subject to the "summoning sickness" rule: It can only attack, and its {T} abilities can only be activated, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
• 10/1/2009: The layering rules have changed. Now if you animate a land and it's power and toughness are lowered by Mutilate or a similar effect, reactivating the land's ability won't reset the values. This is because you apply all effects that set power and tougness to specific values before you apply any that modify power and toughness, regardless of the order in which the effects resolve.
