Slow Djinn

{1}{b}: Regenerate Slow Djinn (The next time this creature would be destroyed this turn, it isn't. Instead
tap it, remove all damage from it, and remove it from
combat.)
{3}: Switch Slow Djinn with a Djinn card in your
hand. (If a creature is tapped, the switched creature
is tapped. The same is true for untapped, attacking,
blocking, enchanted, equipped, and targeted. Any
counters on a creature are on the switched creature
instead.)
