Ok, sorry if this has been asked asked, but I was curious why jade shield does not reflect poison or black hole when cast as a spell against me as a target. I thought that shields that reflect spells(esp. when you try to heal yourself, it bounces off your shield and heals your opponent) against you should reflect poison, heal, black hole, holy light, siphon life, etc......At least that is the way I understand the card; when it comes from a creature, but not from a spell that makes it an ability, so could somebody please help clarify
