I agree with Spiderman, as long as "some" means a lot. I mean, some cards are far more powerful than newer versions of them, but it's not like Alpha is chock full of powerful cards. Dark Ritual, Lightning Bolt, Ancestral Recall, Timetwister, Wheel of Fortune, the dual lands, the moxes, Black Lotus, Sol Ring, Time Walk, Mana Vault, Balance, Fastbond, Black Vise, The Rack, Nevinyrral's Disk, Sinkhole, Berserk, Channel, Mind Twist, Hypnotic Specter, and some other cards seem to have been deemed too strong.
But there are plenty of cards in the original set that have been replaced by something better at some point. Prismatic Lace replaces all of the old laces (although it can't hit spells). Pearled Unicorn and friends have of course been replaced. There are some other obvious ones, but even good very good cards have seen broken replacements at some point. Counterspell is no longer printed because it's considered too good. Mana Drain makes Counterspell look pathetic. Braingeyser has seen time on the Type I restricted list, ever since Urza's Saga, Stroke of Genius has been used over it.
So, many cards will go beyond the limits that Alpha set on its cards. Of course, it is certainly true that some limitations on card capabilities were decided earlier than others. Ancestral Recall has been known as too good for however long it's been now. There is no mention of anything as absurd as printing something with that kind of drawing power again. Wheel of Fortune, on the other hand, was reprinted in Revised and then seen again in the form of Windfall and as an artifact with Memory Jar. Timetwiser reappeared as Time Spiral. Black Lotus became Lion's Eye Diamond, which was eventually found to be too good itself...
