I don't have its name any more - I don't save other people's stuff - but there was a card on custom mtg that was just a sorcery with 'learn, storm' and it was called Cram Session and the way of having a card with like, six words on it, and two of it were its name was amazing.
I also really liked Chainsawinsect's 'strangely spacious tunnel' which was a colourless land you could discard to make an enormous wurm token.
