Shield of the Oversoul (JA)

Enchant creature
As long as enchanted creature is green, it gets +1/+1 and is indestructible. (Lethal damage and effects that say destroy don't destroy it. If its toughness is 0 or less, it's still put into its owner's graveyard.)
As long as enchanted creature is white, it gets +1/+1 and has flying.
