In escalating you can make a run on all the players if you can cash then take out someone who will give you cards to make 5 or more, then cash again, etc. Time it right, bingo. Now with 7. If there is players with 6 or 7 cards you could cash with 5, have 2 left, take out a 7, and have 9 cards. possible 3 sets, then wham. Or cash holding 7, then kill, get 7 and have 11 cards, woah. I think it would add strategy for sure for very good players who position themselves well and know when they need to cash and when they are a target etc. but for public games you could use this option to really destroy people much easier I think.

However I would be interested in some people playing this way together and stating if it works well or does everyone cash at 5 or before anyway so they aren't a target. I would try them but it doesn't really seem like a good option for gameplay in general with escalating anyhow.
