One, I don't think these are "staples". Yeah, most have been around since the first sets, but the first sets were also the "exploratory" phase of Magic with what turned out to be an unrealistic vision of the game (everyone only having and playing a max cardpool of about two starters), not a rigorous playtesting procedure, and not a deep understanding about the powerful inherent mechanics of the game, namely that drawing cards is god (they kinda got that with Ancestral Recall but didn't fully get it, hence Library of Alexandria and Bazaar of Baghdad).
Two, the reason why they're seen all the time is because of their effects per cc, not because they are "staples". You don't see Pearled Unicorn or Gray Ogre, though they have been around since the beginning and due to that line of reasoning, are also "staples".
Whoa, I said that they were staples which had been around since the beginning of the game. I didn't say that they were staples because they had been around since the beginning of the game. I don't think that they are seen all the time anymore. Nothing in my reasoning would indicate that Pearled Unicorn or Gray Ogre could be a staple.
Anyway, my thinking on these cards, with the exception of probably just the dual lands, is that they can be good (sometimes too good) in the less powerful formats but aren't particularly amazing in Vintage or even Legacy.
Hypnotic Specter: It has potential in monoblack decks in Legacy. I don't think any winning deck in Vintage has used it for quite some time now.
Dual Lands: Total staples in both Legacy in Vintage. They are some of the most useful lands in the game.
Lightning Bolt: Particularly important in Sligh, which does well in Legacy. Vintage decks rarely want it because it is not the best creature removal and hitting players is not often useful (still it has seen at least moderate use).
Swords to Plowshares: Excellent creature removal that is seen in both formats. Almost any deck which can use white considers this for sideboard slots and sometimes maindeck slots.
Kird Ape: Only useful in Zoo decks or other RG beatdown strategies. It's a nice card for certain Legacy decks.
Serendib Efreet: I don't know of any serious tournament decks using this right now. It's a good casual card though.
Hymn to Tourach: Like, the Specter, this thing is perfect for monoblack decks, but is not used at all in Vintage.
Control Magic: It's still good casually. But its effect is not often needed in tournaments, and it can be replaced by things like Treachery.
Counterspell: Quite important in monoblue control. In Vintage, Mana Drain is much better. In both formats, Force of Will is more important. And more often than not, Counterspell is inferior to Mana Leak.
Mishra's Factory: The best manland in the game. It shows up in decks that need such a card.
I don't think anything here is "broken" in the same way that something like Yawgmoth's Bargain or Time Walk is. I don't think any of these cards are chaff either. At least half of them have been at some point, what I would call a "staple."
