Though it smashed the previous records, SPM was "merely" ~41% legendary creatures compared to total cards (~70% of the creatures were legendary). I'm skeptical if they can beat the obscenity of SPM's numbers since that was all fucked up by being an overinflated mini-set, but WotC will likely take that as a challenge.

And here's the percentage data, where SPM blows everything else out of the water. The way it jumps arond from FIN to EOE to SPM is amusing to me.
