That is a really strange way of evaluating cards. You must not have liked Cloudgoat Ranger, and especially not Beguiler of Wills.
The Vanilla Test may seem simplistic to a veteran like you or me, but the thing is, we actually do something very much like the Vanilla Test in our heads automatically whenever we see a new card. Like, when I saw the Zarichi Tiger, I automatically thought, "it better have a good ability to make up for that overpriced body," and I decided that "1W, Tap: Gain 2 life." was probably not enough to make up the gap.It's not a bad idea to teach that heuristic to new players.
And obviously it doesn't apply to creatures with very powerful abilities like Beguiler of Wills or Gigantomancer or Meloku the Clouded Mirror. Although you could still apply it to Cloudgoat Ranger by considering it a 6/6 or a 5/3 flying.
"Proc" stands for "Programmed Random OCcurance". It does not even vaguely apply to anything Magic cards do. Don't use it.
