"Switch" variant

[ViolentSilence]

The version of this game I played at school in the UK was called BlackJack - In addition to the power cards listed in the wikipedia entry, we also used a house rule where you could lay down runs of cards which mitigated the impact of picking up a lot of cards and made the game much faster. Is this something that could be added as a variant to Crazy Eight's? Or would it be better as a separate game entirely?
