You make the card 4

[Iandtormentor]

Enchantment with an activated ability to tutor? Sign me up!

Diabolic Calling {1}{B}{B}{B}
Enchantment

Black spells you control can't be countered.

{2}{B}{B}: Search your library for a card, put it into your hand, then shuffle your library.

I really hope wizards makes something like this we need playable standard tutors.

Ohohohoh I know!
Herald of Destruction  {3}{B}{B}

{B}{B}, sacrifice a nontoken permanent: search your library for a card that shares at least 1 type with the sacrificed card and put it in your hand. (For example, if I sacrifice a creature, I can get an artifact creature or {dryad arbor}) sounds cool and kinda reasonable, no? I submitted it to wizards already too
