SEEK has become much better lately as so many decks are including one of the 10+ CMC Mythic Eldrazi. You pay 2, Exile their Emrakul, the Aeons Torn and go up 15 life. Definitely the bane of Eldrazi fanatics.

Seek becomes much more powerful in Commander/EDH, where card multiples are disallowed.

*Gasp* This + Isochron Scepter means you can tear apart your opponents library by first searching through his/her deck and removing anything that would counter/destroy the scepter/instant. Then work your way down from there e.g. broken monster. Only drawback is you run the risk of reshuffling the deck and having the card s/he wants on the top >.>

With the previously mentioned Isochron Scepter combo, you can use Seek to look at your opponent's library and then Hide to enable milling their whole deck with Tunnel Vision. Assuming, of course, they have at least one artifact or enchantment, but you'd know that by then...

This is a very impressive (and extremely useful) card in the legacy tournament format. A few previous players mention this is like the card Extract. Well that is correct in what the card does, although much more thought can easily be poured into the use of this card, then that of Extract. Any experienced, or competitive MtG player will easily explain the difference between an instant and a sorcery. Sorcery is designed to be a powerful spell that has a greater effect on the current battlefield. If a sorcery goes off, it will usually remove multiple targets, if not defeat your opponent(s) out right at that moment. But thats why they are designed to be played on the owner of the sorcery player's turn, allowing all other opponents to respond if they can. Now an instant will never really have the same tremendous impact on a battlefield, for they are designed to remove a single target (although there are exceptions). But in tournament format, many times it aut... (see all)

A *great* sideboard card for red-splashing Junk. Even ignoring Hide's obvious uses, Seek hoses combo decks that are self-confident enough to run one copy of their kill card, which is an absurdly common practice in Legacy.
Vs Ad Nauseam combo decks: Seek for Tendrils of Agony
Opponent: *immediately fold* ... unless they have a Burning Wish to fetch their only other Tendrils
Vs Natural Order combo decks: Seek for Progenitus
Opponent: ... :( ... especially funny if you cast Seek in response to them playing Natural Order
Vs Doomsday+Shelldock Isle combo decks: Seek for Emrakul, the Aeons Torn
Opponent: ... D: ... it's especially funny if you cast Seek *after* Doomsday resolves
I love that Seek does not require you to declare a card name; you can choose whatever you want after picking through the l... (see all)

Hide should be the usual mode (it's a one-for-one). Seek is lifegain, and it comes in handy at times.

I agree with Vinfera, Seek is like Extract with an alternating amount of life. If you're lucky, you may remove something like the infamous Darksteel Colossus - who could be removed with Hide as well in case he is on the field.
(Unfortunately you can't cast both sides, otherwise you could put him on the bottom and then extract it afterwards)
The split card combines nicely with Isochron Scepter as well. (You'll have the possibility to choose which of both halves you want to cast each time)

For just 
you can potentially gain a substantial amount of life and remove a powerful card at the same time. What's not to like about it?
