[Siegmund]

I have a "Hoyle" from 1924 that, in the section on 5-card draw, mentions the game is sometimes played with elevens and twelves added to make a 60-card pack, so that cards don't have to be reshuffled when eight or ten people play. It also suggests that changing the size of the deck had been used in the past as a trick to throw off good players' senses of what the odds were, but that the trick usually backfired since the good players were better able to adapt to the new conditions than the semi-competent players trying to get an edge from an unfamiliar game were.
