For the first, I would tweak it slightly to say, "If blocking a NT hero, you may increase this character's abilities by 10/10 and/or play an enhancement."
For the second, change the title to either "The Disciples took Him!" or "Lying About the Tomb". I would also focus it more, since right now it's not particularly powerful, and doesn't seem to fit the theme that well. This is just a suggestion for how I'd do it: "Place in opponent's territory. While you have a NT evil character in play, negate all protect and ignore abilities."
