Snow-Covered Lands + Gifts

[brokenbacon]

Hey all,
Just something that's been rattling around in my hollow head lately (Jesus what an echo).
A classic tactic with Gifts Ungiven is to run Snow-Covered Lands in order to make a Gifts pile of Island, Snow-Covered Island , etc.
However, drawing into, and playing Snow-Covered Island is like telling your opponent, "Oh yeah, I run Gifts as well." Now I am not sure whether or not this is something that can be used to one's advantage. It is sort of a statement like "I'M GIFTS AND YOU BEST BE READY FOR MY MADNESS!!!!!!!!!" But on the other hand it's like "Oh yeah it's turn one and I already know he's not on Fish, so he's probably Tezz or Oath." Which is a huge problem.
What I'm asking is this: is it at all advantageous for us to run Snow-Covered Lands at all? Really. How often are you going to make a pile of Island, SCI, Sapphire, and A Call? First of all, you clearly have the blue mana available already to play Gifts..... why not go Academy, Island, Sapphire, A Call? This is just as good a pile (admittedly, if Academy is in play then sub out for something else). Like, in this meta when will you ever want to Gifts for 2 lands that simply add 1 mana?
For the record, I am not stating that this Gifts pile is completely wrong. I am sure that many people have clinched games purely because of Gifting for Island and SCI. I just think that it is such a fringe play that it is not necessary, and the fact that "Snow-Covered Island, go," can give the opponent more information than simply "Island, go."
Thoughts?

This has been discussed before.  From the first page of the search results: linky.  I'm sure other threads can be found addressing this question as well, especially from the time when Gifts was unrestricted.

To recap: information is valuable, and possibly more valuable than the additional lines of play provided by Gifts-ing for regular and Snow lands with the same basic type.  Some nefarious people may play Snow-Covered lands intentionally in the absence of Gifts, be wary.
