Trollhide | Enchantment | Aura | Enchant creature
Enchanted creature gets +2/+2 and has "{1}{G}: Regenerate this creature." (The next time the creature would be destroyed this turn, it isn't. Instead tap it, remove all damage from it, and remove it from combat.) | Steven Belledin
Verdant Haven | Enchantment | Aura | Enchant land
When Verdant Haven enters the battlefield, you gain 2 life.
Whenever enchanted land is tapped for mana, its controller adds an additional one mana of any color. | Daniel Ljunggren
