Official Rulings for Angel of Jubilation
5/1/2012 : Other things may still cause players to pay life or sacrifice creatures, such as a resolving spell or ability.
5/1/2012 : Angel of Jubilation's last ability doesn't look for specific words on other cards. Rather, it stops players from taking specific actions. For example, you couldn't activate an ability with an activation of cost of "Sacrifice an artifact:" by sacrificing an artifact creature (although you could sacrifice a noncreature artifact).
