Genju of the Fens

Enchantment - Aura, B (1)
Enchant Swamp
{2}: Until end of turn, enchanted Swamp becomes a 2/2 black Spirit creature with "{B}: This creature gets +1/+1 until end of turn." It's still a land.
When enchanted Swamp is put into a graveyard, you may return Genju of the Fens from your graveyard to your hand.¹

Gatherer Card Rulings [Nov 2009]

• 2/1/2006: Because of the layering rules, if you have an animatable land, you can play the ability once, and then if it's power and toughness are lowered (but not lethally) by Mutilate or a similar effect, you can reactivate the land to restore them to those numbers.
• 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 played, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
