How would Magic be different if Ancestral Recall were called "Ancestral Memory"? Well, probably not much.
You remember Demonic Attorney, right? It looks like this:
Technically, this is part of one of the few first-turn kills in Alpha (Swamp, Black Lotus, Demonic Attorney, opponent concedes rather than ante another card—okay, it's a bit of a cheat) but the really interesting part is the sentence that got cut from the playtest card. "The game will now count double" didn't really mean anything back before a "match" was defined as "best two out of three games," but it would be fascinating now!
What card could this be? Can you guess? Here's a hint: it's not a unicorn of any sort.
In fact, it's the back of the card! So it could be anything. Maybe even a unicorn, which means that the hint could have been completely wrong. Sorry about that. Anyway, from now on, whenever you see an Alpha playtest card, just know that there's a unicorn on the other side.
