My favorite traditional deck (with playing card insets) has always been the Piatnik deck as it is mass-market, so safe for regular/heavy use as it could be easily replaced:

This is becoming harder to find, however, so I might need to pick another favorite for regular use.
As long as it stays in the "Toy" category on Amazon, it may be around for a while.
