Scorpion2 is a two deck spider with most of the cards dealt out.

In extending Scorpion to two decks, my inclination was to use 6 table piles (like the two-deck Spider).  But this proved way to hard, and the 10 tables makes a better balance with cards hidden in a fourth column also.  This leaves only 4 cards in the hand for when the Scorpion strikes, but they will go on those first four columns.
