My favorite play

I’ve been meaning, for a while, to excerpt a clip of my favorite high-level competitive play ever and post it. Here it is, straight from the finals of Pro Tour Charleston 2006 — Tomohiro Kaji deducing the contents of Celso Zampere’s hand during the process of playing a Mimeofacture:

This is a definite “don’t try this at home” moment — or, more specifically, don’t try this in a timed round (and even Kaji picked up a Slow Play warning from the judge, despite the untimed nature of Pro Tour top eight games). It is also peculiar to the top eight of an event, as your opponent’s exact decklist is not otherwise going to be public knowledge. Regardless, it’s my favorite moment of high-level play because it was, when I first saw it, such a clever and unexpected approach to perfectly determining hidden information based on public information.
And don’t forget that he memorized his opponent’s decklist during lunch.
