Without getting into issues of semantics *too* badly, here's what I think of the situation.
We have a card - either one mentioned, doesn't really matter - that does the following;
- gets pitched to Force of Will, OR
- draws a card AND probably makes Tarmogoyf +2/+2 until end of game, OR
- swings for 3
I don't think pitching to Force is irrelevant, for the same reason that I don't think enabling Goyf is irrelevant, although those cards tend to have more weight in Legacy than Vintage. It's the 'eventual beater' thing that, IMO, is a red herring and is pretty well tossable as a reason to run the card. I know there are no bad threats, but you could do a lot better.
The simple question then, is "Is there a card which can not only pitch to Force of Will, but also draw at least one card and in doing so, make one of the best creatures in the format bigger?" And that question narrows down what either of the mentioned cards should be weighed against.
Even the Goyf thing is more like, "How do I make *my* Tarmogoyf more important than my opponent's Tarmogoyf?" None of the suggested cycling cards can do that.
So really, it's like, "What the better card that pitches to Force and draws at least one card?" and there's kind of a LOT of cards that do it better than either of the cards in this thread.
And there's just no comparing it to Street Wraith, it has an entirely different cost. If we're going off the idea that going from 60 cards to 56 is an issue of putting in cards which require no mana investment to cantrip, then these cards fail that test amazingly.
The more important question you should ask is not "Is there a better card that does these things" but rather "Is there something better to be doing than these things?" Sure, this might be the best Pitch-Discard-Cycle card ever. And maybe Reverent Silence is the best Enchantment Destruction ever. That doesn't mean I will play Silence because the thing it does is not good. I have a whole deck of cards which I can discard to Thirst, about a dozen or more cards which draw me at least one other card, and probably upwards of 25 cards that pitch to Force. I don't find myself drawing good cards, cards which actually do something, and thinking "I wish this card pitched and cycled and discarded well instead of doing a real thing". This might be the best card ever at what it does, but what it does basically sucks so who cares.
